In this work, we carry out a exact performance analysis of dual-hop cooperative amplify-and-forward relaying systems in wireless body area networks over independent and nonidentically distributed Gamma fading channels. In particular, we derive new exact closed-form expressions for the end-to-end outage and symbol error probabilities at arbitrary signal-to-noise-ratios (SNRs) of these systems in terms...
In this paper, we investigate the performance of cooperative amplify-and-forward (AF) multi-relay networks with relay selection strategy over independent and identically distributed (i.i.d.) Nakagami-m fading channels. In this system we study multiuser cooperative relaying to have a secure transmission from source to destination, since transmitted information may be wiretapped by multiple eavesdroppers...
