A performance analysis for cooperative diversity system with best relay selection over
Rayleigh fading channels is presented. We obtain analytical expressions for the probability
density function (PDF), cumulative density function (CDF), and the moment generating
function (MGF) of end-to-end SNR of the system under study. Using these expressions we
derive closed-form expressions for the average symbol error rate (SER), the outage
probability and the average end-to-end SNR gain obtained form relay selection. Using …

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 …
