摘要：This paper analyzes the performance of cooperative amplify-and-forward (CAF) relay networks thatemploy adaptive M-ary quadrature amplitude modulation (M-QAM)/M-ary phase shift keying (M-PSK)digital modulation techniques in Nakagami-m fading channel. In particular, we present and compared theanalysis of CAF relay networks with different cooperative diversity and opportunistic routing strategiessuch as regular Maximal Ratio Combining (MRC), Selection Diversity Combining (SDC), OpportunisticRelay Selection with Maximal Ratio Combining (ORS-MRC) and Opportunistic Relay Selection withSelection Diversity Combining (ORS-SDC). We advocate a simple yet unified numerical approach based onthe marginal moment generating function (MGF) of the total received SNR to compute the average symbolerror rate (ASER), mean achievable spectral efficiency, and outage probability performance metrics.
