Outage Probability of SIR Based SC Macro-Diversity Reception in Gamma Shadowed Rayleigh Multipath Fading Environment

The paper considers signal-to-interference ratio (SIR) based macro-diversity reception with macro level (MaL) selection combining (SC) diversity and three dual branch SC diversity receivers at micro level (MiL) in correlated Gamma shadowed Rayleigh multipath fading environment. Rapidly converging, infinite series expression for outage probability (OP) is obtained, graphically presented and analyzed regarding various system model parameters. Precisely, influence of Gamma long term fading severity parameter of desired signal as well as Gamma long term fading severity parameter of CCI on OP are examined and discussed. Further, MaL diversity system performance analysis also includes the effects of shadowing correlation parameter, average signal power of desired signal as well as average power of CCI.
