Moment generating function-based performance evaluation of amplify-andforward relaying in n?? nakagami fading channels (original) (raw)

Abstract In this study, the authors investigate the error rate performance of amplify-and-forward relaying over N* Nakagami fading channels. This is a recently introduced channel model that involves the product of N Nakagami-m-distributed random variables. Employing the moment generating function approach, the authors derive symbol error rate expressions for a single-relay system under instantaneous power scaling (IPS) and average power scaling (APS) factors at the relay node, that is, variable and fixed gains.
