Abstract

In wireless communication systems, antenna diversity is used to mitigate the effects of fading and cochannel interference (CCI). Dual signal-to-interference ratio (SIR)-based selection diversity system over correlated Rician fading channels in the presence of arbitrary number of correlated Nakagami-m CCIs is studied in this paper. Useful analytical expressions for the probability density function (PDF) and cumulative distribution function (CDF) of SIR at the output of dual selection diversity receiver are derived. These expressions are used to study the outage probability and average bit error probability (ABEP) of the proposed system. Numerical results are also presented to support mathematical analysis.
