Аннотация

The system performances of selection combining over exponentially correlated Nakagami-m channels are analyzed in this paper. Selection diversity based on the signal to interference ratio (SIR) is very efficient technique that reduces fading and cochannel interference influence. Fading between diversity branches and between interferers is correlated and Nakagami-m distributed with exponential correlation model. Very useful closed-form expressions for the output SIR's probability density function (PDF), cumulative distribution function (CDF), and outage probability are obtained, which are the main contributions of this paper. Also, the conclusions about influence of fading severity and correlations between received desired signals and interferences on the system performances, such as outage probability, average-output SIR and amount of fading (AoF), are presented.
