Performance analysis of mobile communication networks in the presence of composite fading, noise and interference

In this paper, the effects of interference on composite fading environments, where multipath fading coexists with shadowing, are investigated. More specifically, important statistical metrics of a single receiver output signal to interference and noise ratio (SINR) are studied, including the probability density function and the cumulative distribution function. Our analysis is also extended to multi-channel receivers and in particular to selection diversity (SD) receivers. For all scenarios, simplified expressions are also provided for the interference limited cases, where the influence of thermal noise is ignored. The derived expressions are used to analyze the performance, in terms of the average bit error probability and the outage probability. The analysis is accompanied by numerical evaluated results, clearly demonstrating the usefulness of the proposed theoretical framework.
