摘要：
Cooperative relay networks in OFDM-based systems have been shown to improve performance in wireless communication systems as a form of spatial diversity, but are not readily available cooperative diversity for M-ary QAM OFDM-based system where the best relay only participates in the relaying. In this paper, we investigate the error rate performance of cooperative Diversity for M-ary. QAM OFDM-based system with best-relay selection. The results present bit error probability of M-ary QAM OFDM-based system with best-relay selection for different values of the numbers of relays (M), the numbers of subchannels and modulation scheme. M-ary QAM OFDM-based system with best-relay selection provides higher performance.
