Abstract :
The presence of turbo-TCM and space-time code modulation constitutes a major channel coding in a transceiver. We have designed and simulated a CODEC by Altera in software, which can be improved by FPGA. We also use turbo coding to increase bandwidth efficiency and BAHL and Viterbi decoding to enhance performance. In this paper, the turbo-TCM and space-time code modulation concatenation can improve decoding speed and enhance coding gain relatively without increasing bandwidth in the wireless communication system. We get very good performance from target FPGA with two receive antennas that can increase power gain with an 8 state 8-PSK for the concatenation of TTCM and STBC.
