The performance analysis of wireless macrodiversity switch and stay receiver in the presence of gamma shadowed Kappa-Mu fading

In this paper, wireless mobile macrodiversity (MaD) system with switch and stay (SSC) receiver and two dual branches microdiversity (MiD) selection combining (SC) structures operating over correlated Gamma shadowed Kappa-Mu (k-μ) multipath fading environment is taken into consideration. Cumulative distribution function (CDF) of MaD SSC receiver output signal is obtained and used for the evaluation of outage probability (OP) of MaD SSC system. Numerical results of the proposed model are shown and analyzed regarding multipath severity, shadowing severity and line-of-sight (LoS) factor. Moreover, the impact of correlation and threshold of SSC receiver on the proposed MaD SSC model is presented and discussed.
