Abstract

From practical and theoretical viewpoints, performance analysis of communications with correlated fading channels is important. In this paper, we exploit a novel approach based on Copula function concept to investigate the impact of correlation of Rayleigh fading channels on communication performances. One of the most convenient ways to describe the dependence between several variables is using Copula functions. For this purpose, by applying the Farlie-Gumbel-Morgenstern (FGM) Copula function, we derive closed-form expressions for outage probability as well as coverage region in a wireless multiple access channel (MAC). It is shown that the fading correlation improves the outage probability and coverage region for negative dependence structure. Specifically, whenever the dependence structure tends to negative values, the outage and coverage region performance improvement is increased. Finally, the efficiency of the analytical results is illustrated numerically.
