摘要

Macrodiversity (MACD) system with MACD selection combining (SC) receiver and two microdiversity (MICD) selection receivers in the presence of Gamma long-term fading, Rayleigh short-term fading, and co-channel interference affected to Rician short-term fading is studied in this article. The closed-form expressions for probability density function (PDF) and cumulative distribution function (CDF) of the ratio of Rayleigh random variable and Rician random variable are presented, and probability density function and cumulative distribution function of MICD SC receiver output signal to interference ratio are derived. These results are used for evaluation of the outage probability ( P ~(out)) of considered MACD system, and the influence of Rician factor and Gamma long-term fading severity parameter on the outage probability is analyzed.
