摘要：
In this paper, we consider the performance of downlink multiuser relay networks (MRN) equipped with a single amplify-and-forward (AaF) relay. We present exact analysis in closed-form for the outage probability of MRN with channel state information (CSI)-based gain relaying in Nakagami-m fading channels. In doing so, we derived a new expression for the cumulative distribution function (CDF) of the highest end-to-end signal-to-noise ratio (SNR) associated with the strongest destination terminal. We demonstrate the impact of the fading severity m and the number of destination terminals on the system performance in unbalanced fading conditions. Numerical results substantiate the validity of our analysis.
