Performance Analysis of Amplify-and-Forward Cooperative Networks with Best-Relay Selection Over Weibull Fading Channels

We analyze and study the performance of amplify-and-forward cooperative diversity communication network with best-relay selection over Weibull fading channel. In this paper, a closed-form expression for the moment generating function (MGF) of the total signal-to-noise ratio at the destination is derived in terms of the tabulated Meijer’s G-function. By the help of this derived MGF expression, we analyze the average symbol error rate (ASER) and outage probability over independent and identical distributed Weibull fading channels for multiple relays. The numerical values of ASER and outage probability expressions are compared with Monte-Carlo simulation result to verify the accuracy of the derivation.
