We present an analytical performance study of selection diversity (SD) with multiple amplify-and-forward relays in independent and identically distributed (i.i.d.) Nakagami-m fading channels. Employing SD is an attractive approach to achieve bandwidth and power efficiencies, by utilizing only a single diversity path with the strongest end-to-end signal-to-noise ratio (SNR) to transmit. For such systems,...
In this paper, we present new closed form expressions for lower bounds on the end-to-end outage probability of a dual-hop, non-regenerative cooperative communication system over independent, not necessarily identically distributed, gamma-shadowed Nakagami-m fading channel. More specifically, we obtain new closed form expressions (in terms of Meijer's G function) for the cumulative distribution function...
Cooperative network is a way to make a reliable communication by adding a relay between the source and the destination. The incremental relaying based on the amplify-and-forward transmission was introduced in (Laneman et al., 2004) as an efficient relaying protocol. In this paper, we provide the performance analysis of incremental relaying with adaptive QAM transmission over the independent, non-identically...
