Multi-source multi-destination wireless relay network coded systems are investigated in this paper. To achieve multiple interpretations at different receivers, we employ nested codes in our proposed system. Besides, an opportunistic scheduling (OS) technique is adopted at the relay to maximize the system capacity. The proposed system model combines the merits of both nested codes and OS. First, we...
Three new power allocation schemes for a typical amplify-and-forward (AF) cooperative system over independent non-identical Nakagami-m fading channels are proposed in this paper. By analyzing the upper bound of the instantaneous SNR (signal-to-noise-ratio) at the destination using the inequity expression between arithmetic mean and geometric mean, we derive the average SNR and SER (symbol-error-rate)...
