PSR-based ANC protocol in energy harvesting bidirectional networks

We study the energy harvesting analog network coding (ANC) protocol in amplify-and-forward (AF)-based bidirectional relay networks consisting of two different sources and a single relay, where each terminal has a single antenna and operates in a half-duplex mode. In the network, there are two opposite traffic flows between the two sources, and the relay harvests energy as well as processes information through the received signal transmitted from the sources with power splitting relaying (PSR). Specifically, for the PSR-based ANC protocol, we obtain the optimum power splitting coefficient to maximize the end-to-end transmission rate, which is given by the minimum mutual information of the two opposite traffic flows, and we derive the outage probability and the maximum transmission rate.
