ABSTRACT: In this paper, wireless mobile communication system in the presence of short term fading, long term fading and co-channel interference subjected to short term fading is considered. Desired signal experiences Nakagami-m short term fading and Gamma long term fading, and co-channel interference experiences Nakagami-m short term fading. In interference limited wireless fading channel, the ratio of desired signal envelope and co-channel interference envelope is important performance measure. In this paper, the closed form expressions for probability density function (PDF) and cumulative distribution function (CDF) of ratio of desired signal envelope and co-channel interference envelope are calculated. By using these formulas, outage performance of proposed wireless communication mobile system can be evaluated. The influence of Nakagami-m multipath fading severity parameter of desired signal and interference signal, Gamma long term fading severity parameter and Gamma long term fading correlation coefficient on outage probabilities are analyzed and discussed.
