Abstract: In this paper, we consider two-way full-duplex relay with energy harvesting system, in which the relay node harvests transmitted power from the two source nodes to forward signals to destinations. We also analyze the relay network model with decode-and-forward protocol for information cooperation and time switching-based relaying protocol for power transfer. In particular, the outage probability, average throughput and optimal energy harvesting time of novel scheme in simultaneous wireless information and power transfer are presented. We obtain analytic closed-form expressions for both tight bounded and asymptotic of outage probability and average throughput of system. Using numerical and analytic simulations, the performances of different situations are presented and discussed more clearly. The results show that the better performance is achieved in case of worse self-interference. As important result, the better self interference cancellation leads to superior system performance.
