This paper investigates the performance of cooperative relay networks in the presence of hybrid automatic repeat request (ARQ) with delay constraint. It analyzes the scenarios where the relay channels are asymmetric (i.e., the links of the wireless relay network follow different fading distributions) due to relaying position and/or due to time varying channel fading. The analytical expressions for...
In this paper, the throughput of relay networks with multiple source–destination pairs under queueing constraints has been investigated for both variable-rate and fixed-rate schemes. When channel side information (CSI) is available at the transmitter side, transmitters can adapt their transmission rates according to the channel conditions, and achieve the instantaneous channel capacities. In this...
We consider a wireless energy harvesting (EH) relay network, in which the relay harvests energy from the source node. Considering a power splitting (PS) protocol, performance measures such as average signal-to-noise ratio (SNR), outage probability and throughput are analyzed. Subsequently, optimal PS ratios are analytically derived in order to maximize the instantaneous SNR and throughput. All theoretical...
