LTE Downlink Shared Channel Processing with GPU Acceleration
This example shows how you can use GPUs to accelerate bit error
rate simulations. This example uses a portion of the transport
channel processing for the Downlink Shared Channel (eNodeB to
UE) of the Long Term Evolution (LTE) specification developed by
the Third Generation Partnership Project (3GPP) [ 1]. For more
information see the Downlink Transport Channel (DL-SCH)
Processing example.  You must have a Parallel Computing Toolbox™
license to run the GPU portion of this example.    Launch the
GUI   Overview of the Simulation  This simulation models part of
the Downlink Shared Channel of the LTE system. The LTE
specification allows transport blocks that exceed 6144 bits to
be segmented into smaller subblocks. Each of these subblocks is
turbo encoded separately, and each has a CRC applied. A per-
transport block CRC is then appended. Given this scheme,
decoding of the subblocks can be done
