In this paper, they consider a Two-Way Relay Network (TWRN) with non-coherent differential binary phase-shift keying modulation, where a battery-free relay node harvests energy from the received Radio Frequency (RF) signals and uses the harvested energy to help the source nodes for information exchange. Based on the Power Splitting (PS) and Time Switching (TS) receiver architectures, Power Splitting Relaying (PSR) and Time Switching Relaying (TSR) protocols at relay are studied. In order to investigate the effect of power allocations on two source nodes, power splitting coefficient and time switching factor at relay on performance, the two proposed protocols are analyzed and the Bit Error Rate (BER).
