Multiple-antenna (MIMO) technology is becoming mature for wireless communications and has been incorporated into wireless broadband standards like LTE and WiFi. Basically, the more the number of antennas the transmitter/receiver is equipped with, the more the possible independent signal paths and the better the performance in terms of data rate and link reliability. Massive MIMO (also known as large-scale antenna systems, very large MIMO, hyper MIMO and full-dimension MIMO) makes a clean break with current practice through the use of a very large number of service antennas (e.g., hundreds or thousands) that are operated fully coherently and adaptively. Extra antennas help by focusing the transmission and reception of signal energy into ever-smaller regions of space. This brings huge improvements in throughput and energy efficiency, in particularly when combined with simultaneous scheduling for a large number of user terminals (e.g., tens or hundreds). This Paper focuses on the efficiency of the throughput and fairness of large MIMO. In multi-user MIMO (MU-MIMO), fewer antennas were used, so the only concern was to mitigate the interference of the users. The interference was mitigated by using zero forcing (ZF) receivers while the fairness of the system was maintained by using Rayleigh Fading channel. MU-MIMO was sufficient for only smaller number of users as the number of antennas were fixed and all the users had to be entertained within the same bandwidth. But, in Massive MIMO, along with the interference of the users, the interference of the antennas themselves is also a big concern, as, the number of antennas were increased contrary to the fixed fewer number of antennas in MU-MIMO. Rayleigh Fading channel and ZF receivers were not sufficient for increased number of users and antennas respectively.

Wireless communication has a very important role in the day to day life for everyone. The wireless technology is growing rapidly and there is a growing demand of high performance, capacity and larger bit rate wireless communication systems which cope wireless communication services such as high speed data, video and voice signals. Multicarrier modulation scheme like OFDM provides an efficient solution to overcome this problem. In this paper a gray scale image processing is done using a LMS algorithm with wavelet based OFDM system using the QPSK modulation scheme in AWGN and Rayleigh channel in SISO environment and results are compared with the conventional adaptive FFT based OFDM system. We reconstruct our transmitted signal at receiver; in both systems by minimizing the error by adaptive filter but the computational complexity of FFT based system is more as compared to DWT based system. Results are compared in term of SNR vs BER which shows that adaptive DWT based OFDM system perform better as compared to the conventional adaptive FFT OFDM system.

Filter Bank Multicarrier (FBMC) transmission technique is a primary candidate for upcoming wireless communication standard 5G. It is also considered as an alternative to the famous Orthogonal Frequency Division Multiplexing (OFDM).To ensure interference free communication, OFDM utilizes Cyclic Prefix (CP) along with a rectangular pulse shaped filter. Which renders OFDM spectrally inefficient, when incorporated over large arrays of antennas. The FBMC can overcome this problem by using a different modulation scheme and a specialized prototype filter. We started this study by presenting a detailed analysis of an FBMC system. Furthermore, the FBMC system is interfaced with a Multiple Input Multiple Output (MIMO) antenna system with different antenna array sizes. We begin with a 2X2 antenna array and then we perform experiments with 8, 16 and 32 transmit and receive antennas. Signaling and channel specifications are different for each case. The performance of each system is measured using Zero forcing (ZF) and Minimum
Mean Square Error (MMSE) equalizers. Bit Error Rate (BER) is measured against normalized Signal to Noise Ratio (SNR) or Eb=No for each system. The results of this study show that FBMC
with MIMO depicts a satisfactory improvement in performance For the 2X2 MIMO system MMSE outperforms the ZF equalizer.Moreover, a significant decrease in BER was observed as the array size was increased.

This paper considers the Semi Round Robin Scheduling (SRRS) tactics that relates different pairing norms to select a pair of users carrying out transmission simultaneously in uplink Virtual Multiple Input Multiple Output (VMIMO) system for Long Term Evolution (LTE). Five different procedures
are defined and matched, which are regarded as capacity maximization and complexity reduction. The system throughput and user fairness are analyzed and simulated. As results show SRRS
scheme gives a tradeoff between the throughput and fairness in Single User VMIMO (SU-VMIMO) and Multiple User VMIMO (MU-VMIMO). VMIMO with SRRS approach will remarkably improve the system throughput and can achieve the fairness up to 99%.

In any sport, where many players work as team, the fitness level of every single player directly affects the overall performance of the team. Beside injuries and many other game related illnesses, the most problematic thing that players usually suffer from is the muscle fatigue. Scientists are sure that the level of fatigue in an over worked muscle can be measured by measuring PH value of the blood. This is because an overburdened muscle has slightly acidic PH value than normal. This acidity is due to the production of excess lactic acid in the blood. In this research work we use in-vivo sensors to measure fatigue in field hockey players and then transmit that information to health officials of the hockey team using Wireless Body Area Network (WBAN). WBAN in our proposed design consists of multiple sinks mounted around the ground.

In this work, we consider the use of multiple antenna signaling technologies, specifically space-time block coding (STBC) and spatial multiplexing (SM) schemes, in multiple-input multiple-output (MIMO) communication systems employing dual polarized antennas at both ends. The use of dual-polarized antennas  theoretically double the number of virtual antennas used in the system. On the other hand, the correlation effects and the  cross-polar discrimination (XPD) deteriorates the system performance. In our work, we consider these effects and present
model of a 3 × 3 system with triple-polarized antennas for both
STBC and SM cases. We also present simulation results for
both multi-antenna signaling techniques together with hybrid
approaches under various XPD and correlation scenarios. The
simulation results show a significant performance gain by joint
utilization of space, time and polarization diversity in comparison
to uni-polarized systems with the same number of antennas. We
observed that dual and triple polarized systems have different
performances at various channel scenarios. Antenna selection
performs better for systems with space time coding and boosts
the performance more in triple-polarized MIMO compared to its
dual-polarized counterpart.

Cross-polarized antenna selection schemes lead to a significant reduction in cost and hardware size without sacrificing the advantages of multiple-input multiple-output systems. In this work, we present a study of receive antenna selection based on measurements obtained with a tripole antenna pair. From the measurement data we extract the selection gains associated with triple polarized channels for a different number of antenna
combinations at the receiver. The obtained results show the
effectiveness of dealing with antenna selection schemes along with orthogonal antennas, providing higher gains in most of the cases

Antenna subset selection in combination with dualpolarized antennas offers a better solution for compact and low-complexity devices using higher order Multiple-Input Multiple Output (MIMO). In this paper we provide another degree of freedom to the existing dual-polarized MIMO and analyze the performance of antenna selection for triple-polarized MIMO systems with maximum ratio combining receivers. We theoretically analyze the impact of cross-polar discrimination on the achieved antenna selection gain for both dual and triplepolarized MIMO for non line of sight channels. We proceed to derive the outage probabilities and observe that these systems achieve significant performance gains for compact configurations with only a nominal increase in complexity. We observe that at higher cross polarization discrimination and lower transmit signal to noise ratio, the outage performance for a dual-polarized system is almost the same as triple-polarized system with joint transmit/receive antenna selection. With selection at only one end of the link, the triple-polarized system performs better than dual-polarized counterpart at higher values of transmit SNRs.We also found out that the available degrees of freedom significantly increase with lower values of cross polarization discrimination.

In this paper, we present a low complexity approach to receive antenna selection for capacity maximization, based on the theory of convex optimization. By relaxing the antenna selection variables from discrete to continuous, we arrive at a convex optimization problem. We show via extensive Monte-Carlo simulations that the proposed algorithm provides performance very close to that of optimal selection based on exhaustive search. We consecutively optimize not only the selection of the
best antennas but also the angular orientation of individual antenna elements in the array for a so-called true polarization diversity system. Dual and triple polarized antenna structures are a very good solution for realizing compact devices and also robust
against many imperfections as compared to spatially separated antenna structures. Effectively we extend our work from two dimensional antenna structures to three dimensions. We model such polarized antenna systems and then apply convex optimization theory for selecting the best possible antennas in terms of capacity maximization. Channel parameters like transmit and receive correlations, cross-polarization discrimination
(XPD) are taken into consideration while modeling polarized systems. We compare our results with the Spatially Separated (SP) MIMO with and without selection by performing extensive Monte-Carlo simulations. We found that by using convex optimization algorithm, the performance of multiple polarized systems can be significantly enhanced. For certain channel conditions we observe that triple polarized systems increase the performance significantly compared to dual-polarized and spatially
separated systems. We observed that applying selection at the receiver only boosts the performance in Non Line of Sight (NLOS)
channels compared to Line of Sight (LOS) channels

Recent technologies have made real-time high data rate communication a reality. Long Term Evolution (LTE) is one of them. In this paper we discuss the performance of Transmit Diversity (TxD) and Spatial multiplexing (SM) using Multiple Input Multiple Output (MIMO) communication in comparison with Single Input Single Output (SISO) communication to achieve high data rates in LTE communication. Vehicular A (VehA) and Vehicular B (VehB) tapped delay channel model are used to model the high speed outdoor movements of the LTE user. Soft Sphere Decoder (SSD) with Minimum Mean Square Error (MMSE)
equalization is used. Sphere decoder (SD) gives a sub optimal
Maximum Likelihood (ML) solution with reduced complexity.
Complexity is reduced as compared to the ML decoder as the
solution is chosen by considering the values that are enclosed by
the radius of the sphere. Soft decisions are incorporated to have
reduced error probability. The comparison is performed between
transmission modes to select the mode of communication based
upon the SNR and throughput to achieve optimal utilization of the resources. It is observed that at lower values of SNR, TxD performs better, giving higher throughput and reduced Block Error Rate (BLER). As the SNR values are increased beyond a certain threshold, the performance of Closed Loop Spatial Multiplexing
(CLSM) and Open Loop Spatial Multiplexing (OLSM) performs better than the TxD in terms of throughput therefore making TxD not suitable for higher values of SNR. The Least Square (LS) estimation for feedback provides no improvement at high speed to compensate the rapid change of the channel behavior.

Diversity and achievable rate can be enhanced by using multiple-input multiple-output (MIMO) systems. This directly increases the overall cost due to increase in the radio frequency chains for each antenna element. The issue can be resolved with antenna selection techniques at the transmitter or the receiver by using a small number of RF chains. These RF chains are multiplexed between larger number of transmitter/receiver antenna elements. Dual and triple polarized antenna structures
are a very good solution for realizing compact devices and also robust against many imperfections as compared to spatially
separated antenna structures. We model such polarized antenna
systems and then apply convex optimization theory for selecting
the best possible antennas in terms of capacity maximization.
Channel parameters like transmit and receive correlations, crosspolarization discrimination (XPD) are taken into consideration while modeling polarized systems. We compare our results with the Spatially Separated (SP) MIMO with and without selection by performing extensive Monte-Carlo simulations. We found that by using convex optimization algorithm, the performance of multiple polarized systems can be significantly enhanced.For certain channel conditions we see that triple polarized systems increase the performance significantly compared dualpolarized and spatially separated systems. We observed that applying selection at the receiver only boosts the performance in NLOS channels compared to LOS channels. We also found that convex optimization based search method performs better than conventional exhaustive search based antenna selection for polarized MIMO systems.

The objective of this paper is to evaluate the performance of dual-polarized Multiple-Input Multiple-Output (MIMO) systems, compact in antenna array size and with reduced radio frequency complexity. We compare co-located antenna array structures with their spatial counterpart while deploying receive antenna selection. To this purpose, the performance in terms of MIMO maximum mutual information is presented. A simple norm based on instantaneous channels selects the best antennas. We derive explicit numerical expressions for the effective channel gains. These expressions are precise for small values of NS and NR, and approximately valid for higher values of NS and NR, NS and NR being the number of selected and total receive antennas, respectively. Further a comparison in terms of power imbalance between antenna elements is presented. We conclude that angularly separated compact antenna arrays with a few simple monopoles, if used with antenna selection can provide a better performance compared to a conventional Uniform Linear Array (ULA). We also show that co-located structures are robust to power imbalance and orientation variations compared to a ULA.

In this work we analyze the combined effects of array orientation/rotation and antenna cross polarization discrimination on the performance of dual-polarized systems with receive antenna selection. We start our analysis with a 1 out of N selection and extend it to M out of N receive antenna selection, for which we derive numerical expressions for the effective channel gains. These expressions are valid for small values of M and N, and approximately valid for higher values of M and N. Our analysis shows that robustness against rotation increases as the number of selected antennas is increased. We conclude from our analysis that M needing to be at least 1/2 of N, the maximum effective channel gain can be attained.

A critical factor in the deployment of multiple input multiple-output systems is the cost of multiple analog transmit/receive chains. This problem can be mitigated by antenna subset selection at the transmitter/receiver. With antenna selection, a small number of analog radio frequency chains are multiplexed between a much larger number of transmit/receive antenna elements. In this paper, we present a low complexity approach to receive antenna selection for capacity maximization, based on the theory of convex optimization. By relaxing the antenna selection variables from discrete to continuous, we arrive at a convex optimization problem. We show via extensive Monte-Carlo simulations that the proposed algorithm provides performance very close to that of optimal selection based on exhaustive search. We consecutively optimize not only the selection of the best antennas but also the angular orientation of individual antenna elements in the array for a so-called true polarization diversity system.

Antenna subset selection methods are feasible to reduce the hardware complexity of multiple-input multiple-output (MIMO) systems. Numerous methods have been devised to resolve this problem. Most of these selection schemes were applied to specific system models and for frequency flat systems. In broadband systems like WiMAX (IEEE 802.16-2004), the overall channel under consideration is typically frequency selective, and flat only over the subcarrier bandwidths. In this work, receive antenna subset selection schemes are applied to a WiMAX compliant MIMO-OFDM transmission system. Simulation results in terms of average throughput and BER on an adaptive modulation and coding link are shown. Very unexpectedly we find that the optimal selection for maximum throughput, does not give the best results in terms of BER performance. We thus conclude that minimum BER is not the right choice for antenna selection. We also find through our simulations that the simple, low complex norm based selection algorithm, provides good results, close to optimal selection in frequency selective channels.

Objective: To propose a wavelet-based template matching technique to extract features for automatic classification
of electrocardiogram signals of normal and arrhythmic individuals.
Methods: The study was conducted from December 2014 to December 2015 at the Department of Electrical
Engineering, Institute of Space Technology, Islamabad, Pakistan. Electrocardiogram signals analysed in this study
were taken from the freely available database www.physionet.org. The data for normal subjects was taken from the
Massachusetts Institute of Technology-Beth Israel Hospital's normal sinus rhythm database and data for diseased
subjects was taken from the arrhythmia database.
Results: Of the 30 subjects, there were 15(50%) normal and 15(50%) diseased subjects. The group-averaged phase
difference indices of arrhythmic subjects were significantly larger than that of normal individuals (p<0.05) within the
frequency range of 0.9-1.1 Hz. Moreover, the scatter plot between the phase difference index and magnitude of
wavelet cross-spectrum for frequency range of 0.9-1.1 Hz demonstrated a satisfactory delineation between normal
and arrhythmic individuals.
Conclusion: Wavelet decomposition-based template matching technique achieved satisfactory delineation of
normal and arrhythmic electrocardiogram dynamics.

The performance of UFMC is also analyzed for 2x1 Alamouti Space Time Block Codes (STBC) and 2 x 2 MIMO STBC schemes using Maximum Likelihood (ML) detector. The simulation results show that by applying multi-antenna techniques in UFMC offers better performance than OFDM in terms of SER vs SNR. The 2x1 Alamouti STBC gives 1.12 times more diversity gain in UFMC as compared to OFDM and 2 x 2 MIMO STBC for UFMC provides 1.86 times
more diversity gain as compared to OFDM. Among the detectors, MMSE shows the optimal performance for UFMC at both low and high SNR values.

We develop a system that reconstructs and models in 3D for unknown structures and environments using autonomous robot equipped with a radio transceiver in real time. The indoor wireless scanning would be conducted with the help of a smart antenna array which uses  narrow beam highly directional antenna beams. These beams would scan the environment and the obstacles within in 2D initially and then all the 2D models would be combined together to form a 3D model.  The data collected can be stored in the robotic system and processed online or can be transferred to a remote system where after processing a 3D model is constructed in real time. The raw data received from the robot can be processed to display the unknown environment in 3D on a computer or construct it in a holographic view.

This projects aims to design an open and modular architecture of a testbed for experimentation in cooperative algorithms, techniques and applications involving robots and WSNs. Currently, we want to design flexible robots and motes for the testbed which is easily extensible and has good scalability properties. The main experiments would focus on WSN network formation and recovery and robot localization.

Wireless Sensor Networks for Disaster Management systems
The goal of the test bed is to characterize performance over realistic propagation and interference environments. These environments have statistical variations on the performance that are a function of the absolute position of the antennas. Manually moving the antennas to collect statistically significant observations and data is not a creative use of engineering time. For this reason we have chosen to develop a test bed that has the ability to remotely move antenna positions. This remote control will allow significant amounts of data to be collected without noteworthy man power being spent in monitoring and implementing the tests. The robotic system will be implemented with Lego components to keep the cost and electro-magnetic interaction with equipment to a minimum. A MIMO test bed must be able to provide benchmarks for performance to give context for the measured results. In simulation studies, the benchmarks are provided by Claude Shannon and information theory. In simulation studies, the channel is known and the benchmarks are easily computed. In experimental systems the channel is unknown, hence reporting results without a channel measurement and capacity estimation is not useful. For this reason we have chosen to develop a test bed that has the ability to quasi simultaneously measure system capacity and measure performance of realistic coding and modulation schemes on the measured channels.

In this research we will investigate various wavelets and various transforms to different aspects of OFDM and MIMO. We will replace conventional DFT and FFT in OFDM and see the advantages we can get. We will implement different wavelets and see the performance. Also we will perform hard antenna selection for MIMO by replacing DFT with DWT and analyze the performance with simulations and mathematical models.
Application of wavelets and wavelet transforms to MIMO-OFDM systems
Traffic management issues cause accidents around the world incurring a huge loss in terms of money and infrastructure. In a third world country like Pakistan, this issue pertains to absence of any efficient traffic management system due to lack of utilization of recent communication technologies and standards. Here we are proposing a complete system for this purpose. The system is based on vehicular communication using Wireless Sensor Network technology. We are going to propose protocols and framework using communication and information technologies for car to car and car to infrastructure road safety as well as traffic efficiency applications. We will design and implement vehicular communication safety system based on the proposed protocols and framework.
Automated Traffic Management and Safety System
The final goal of this research is to deploy a constellation of HAAPs (High Altitude Aeronautical
Platform) to provide inflight internet and telephone services. People nowadays always want to
remain connected whether to remain in touch with their loved ones or to keep a close eye on the
business. Since the HAAPs are usually deployed above the air traffic it can provide a low cost
solution for the provision of inflight mobile and data services that can bring substantial revenue to
both the flight carrier and the mobile operators.
Moreover, the same HAAP can be equipped with GPS (Global Positioning System) like
transmitters in order to provide a navigation solution to the users. The Navigation payloads will
transmit timing signals in the L‐band which the receiving user can decode in order to find its
precise location. The constellation can also be used as a disaster management network in the
absence of the primary wired network.
HAAPs (High Altitude Aeronautical Platform) to provide inflight internet and telephone services.
This project investigates the possibilities and usage of MIMO techniques (already used in terrestrial NW's) in Satellite systems. The idea is to see if using multiple antennas and Space Time algorithms could increase the performance in LMS systems or not. This project also includes defining new architectures for relaying through HAPS systems with Satellites and terrestrial systems.
