Abstract

The performance of dual-hop transmission system operating over independent and non-identical Nakagami-m fading channels in the presence of co-channel interference is studied. Exact and upper-bound expressions for the signal-to-interference-plus-noise-ratio (SINR) at the destination are formulated. Then, the cumulative distribution function (CDF) and probability density function (PDF) of the upper bounded SINR are determined. Furthermore, closed-form expressions for the error and outage probabilities are obtained and discussed. Moreover, an approximate PDF of the dual-hop link´s instantaneous SINR is derived. Based on said PDF, simple, yet general, asymptotic expressions for the error and outage probabilities are presented and discussed. Numerical and simulation results are provided to verify the tightness of the presented analysis.
