On the Performance of Cooperative Systems with Blind Relays over Nakagami-m and Weibull Fading

Abstract

In this manuscript, we propose an accurate framework for the analysis of cooperative dual-hop wireless systems over fading channels, which use an Amplify and Forward (AF) relaying mechanism with fixed-gain relays. In particular, the proposed framework provides either exact results or very accurate bounds for computing the Moment Generating Function (MGF) of the end-to-end Signal-to-Noise Ratio (SNR) over Nakagami-m and Weibull fading. Furthermore, with the help of the MGF-based approach for performance analysis of wireless systems over fading channels, we will show that important performance indexes can be easily derived from the MGF. Numerical results will be shown to substantiate the proposed analytical framework.
