Abstract :
In this paper, a space-time trellis code (STTC) concatenated with space-time block code (STBC) for multi- carrier code-division multiple-access (MC-CDMA) system in the multi-path fading channel is considered, and the performance of the system is evaluated through simulations. The corresponding bit error rate (BER) of the concatenated STTC-STBC-MC-CDMA system is compared with STTC-MC-CDMA system. The results show that the improved performance can be achieved by concatenated STTC-STBC-MC-CDMA system having 16 states STTC.
