Abstract
Simultaneous wireless information and power transfer (SWIPT) is a promising communication solution for energy-constrained wireless network. In the practical environment, the interference often results in a loss of the system rate, but it also brings energy at the same time. This paper proposes the scheme of interference energy harvesting (IEH) which can compensate for the loss of the SWIPT relay system rate caused by the interference. Based on the existing two operation strategies, time switching (TS) and power splitting (PS), we investigate the effect of IEH on the relay system rate. The interference energy is divided among subsequent transmission blocks, which can reduce the duration of energy harvesting (EH) slots. In addition, the optimal points are investigated in the different interference factors and interference power. The results show that IEH can effectively improve the relay system performance under an interference channel.
