A dual selection combining (SC) receiver which applies desired signal power algorithm and operates over correlated, but not necessary identically distributed Nakagami-m fading channels in the presence of cochannel interference (CCI) is considered in this letter. Actually, a novel infinite-series expression for the average level crossing rate (LCR) at the output of that SC receiver is obtained. Numerical results are presented to examine the effects of the fading severity, input signal-to-interference ratio (SIR) unbalance and the level of branch correlation on the average LCR, as well as the correctness of proposed analytical formulation.
