Wireless communication system operating over Gamma shadowed multipath fading channel in the presence of cochannel interference subjected to small scale fading is delineated in this paper. Desired signal experiences Gamma long term fading, k-mu short term fading and cochannel interference affected by k-mu multipath fading. In interference limited environment, the signal to interference ratio (SIR) for proposed wireless communication system can be calculated as the ratio of product of square rooted Gamma random variable and k-mu random variable and k-mu random variable. The probability density function (PDF), moments and moment generating function of signal to interference ratio will be calculated as expressions in the closed form. The impact of Rician factor of desired signal and Rician factor of cochannel interference on moments will be analyzed and discussed.
