Two-way interference-limited AF relaying with wireless power transfer

Energy harvesting relaying is a promising solution to the extra energy requirement at the relay. In this paper, the outage probability of two-way amplify-and-forward relaying system using energy harvesting techniques is proposed. The analysis takes into account both the Nakagami-m fading caused by signal propagation and the interference at relay caused by other transmitters. The relay harvests energy from both end-sources as well as the interference from other transmitters on it. Simplified high SNR result is also deduced. Numerical results confirm the correctness of the proposed analysis.
