Performance Analysis of Cooperative MTM Communication with Equal Gain Combining
摘要
Abstract
A cooperative communication scheme with equal gain combining (EGC) is presented to deal with the severe double fading channels in mobile-to-mobile (MTM) systems.Performance analysis of this scheme is addressed for the dual-hop decode-and-forward (DF) protocol.Double Nakagami-m fading is assumed for the considered MTM channels.The approximate expression of the moment-generating function (MGF) of the output signal-to-noise ratio is firstly provided by using the Padé approximation.Furthermore,the closed-form expression of the approximate symbol error rate is derived for M-phase-shift keying modulation.Simulation results show that the theoretical results match the corresponding simulation curves under various channel parameters.Compared with optimum maximum ratio combining,the performance degradation caused by EGC is about 1 dB.关键词
