Prof. Bajwa Awarded U.S. Patent


Dr. Waheed Bajwa was awarded US patent 8,320,489 B2 "Determining channel coefficients in a multipath channel".

In wireless telecommunications, signals are transmitted and received over transmission channels within a limited range of frequencies, typically between 0.7 GHz to 6 GHz for domestic applications. Due to the limited amount of transmission space, it is increasingly important to perfect techniques that estimate channel state information (CSI) at the transmitter and/or receiver to maximize wireless performance over the multipath channels. In modern communication systems training-based channel learning techniques are commonly used to retrieve the CSI at the receiver, which can improve communication efficiency, particularly in terms of power and spectral efficiency.
