A very efficient technique that reduces fading and channel interference influence is selection diversity based on the signal to interference ratio (SIR). In this paper, system performances of selection combiner (SC) over correlated Nakagami-m channels with constant correlation model are analyzed. Closed-form expressions are obtained for the output SIR probability density function (PDF) and cumulative distribution function (CDF) which is main contribution of this paper. Outage probability and the average error probability for coherent, noncoherent modulation are derived. Numerical results presented in this paper point out the effects of fading severity and correlation on the system performances. The main contribution of this analysis for multibranch signal combiner is that it has been done for general case of correlated co-channel interference (CCI).
