The end-to-end performance of dual-hop cooperative diversity systems equipped with nonregenerative relays and a selection combining receiver at the destination terminal over independent and nonidentical Nakagami- fading channels is studied.Closed-form expressions for the cumulative distribution function and the probability density function of the end-to-end signal-to-noise ratio ( ) are presented, while analytical formulae are derived for the moments and the moment generating function.Using these kashayam dress statistical results, closed-form expressions for the outage probability are presented for both channel state information and fixed gain relays.Furthermore, for the case of fixed gain relay, the average end-to-end , the amount of fading, and the average bit error rate can be numerically evaluated.The proposed mathematical analysis is complemented rjr-00001 by numerical examples, including the effects on the overall performance of the s unbalancing as well as the fading severity.
