Outage P?rformance of Wireless System in the Presence of KG Short Term Fading and Co-channel Interference

In this paper, wireless mobile communication radio system in the presence of long term fading, short term fading and co-channel interference will be analyzed. Desired signal and cochannel interference experiences Nakagami-m short term fading and Gamma long term fading. Probability density function and cumulative distribution function of the ratio of two KG random variable are obtained as the closed form expressions. Probability density function can be used for calculation the bit error probability and cumulative distribution function can be used for evaluation the outage probability. In interference limited environment, signal to interference ratio is important performance measure of wireless system. The influence of Nakagami-m short term fading severity parameter and Gamma long term fading severity parameter on the outage probability will be examined.
