Outage probability of interference-limited system over Weibull-gamma fading channel

The outage performance of a receiver operating over the gamma shadowed Weibull multipath fading channel in the presence of a co-channel interference is determined. The novel analytical expressions for the probability density function, cumulative distribution function and moment generating function of the system´s signal-to-interference ratio (SIR) are derived. The outage probability dependence on shadowing spread, multipath fading severity and average SIR are determined. The analytical results are confirmed by simulations.
