An FPGA Implementation of TCM Cascade Space Time Block Code

Trellis coded (TCM) modulation can obtain the coding gain without increase the transmission power and the bandwidth but it can not obtain diversity gain, and space-time block code (STBC) can provide diversity gain in a simple encoding and decoding way, though its coding gain is not very satisfied. This article will achieve a STBC-class networking trellis coded modulation scheme based on FPGA to further study the performance of the concatenated code.
