N2 - This paper studies the performance of multiple relays amplify-and-forward (AF) cooperative communication system with adaptive M-QAM modulation in Rayleigh fading channel. The average spectral efficiency of the fixed and adaptive rate MQAM scheme are both researched and analyzed. We come into the conclusion that under certain BER level, the adaptive MQAM scheme achieves significant efficiency gains over the nonadaptive one. Besides, we obtain the spectral efficiency loss for the fixed rate M-QAM scheme resulting from the increase of the number of the relay nodes which are confirmed can in a great extent be compensated for in the adaptive one. In addition, the simulation of probability of outage for the rate-adaptive M-QAM modulation system exhibits that the adaptive scheme can acquire high successful transmission rate as well as guarantee the bit error rate.
