We consider power allocation (PA) and relay positioning in a dual-hop regenerative relaying system with multi-antenna destination node in Weibull fading environment. With the fixed relay location, adaptive PA at the source and relay nodes under joint power constraint and with the aim to minimize the average error probability at high signal-to-noise ratios (SNRs) is presented. Then considering fixed...
This paper addresses the power allocation and relay positioning problems in Amplify-and-forward cooperative networks over Weibull fading channels. We study adaptive power allocation (PA) with fixed relay location, optimal relay location with fixed power allocation, and joint optimization of the PA and relay location under total transmit power constraint, in order to minimize the outage probability...
