摘要：
In order to improve the system sum rate and energy efficiency of cognitive radio networks, this paper first gives a two-way amplify-and-forward (AF) relay scheme based on radio frequency (RF) energy harvesting and X-duplex. Energy harvesting technology is used to obtain energy from RF signals to achieve the simultaneous transmission of information and energy. At the same time, the interference signal is converted into energy to supply energy for energy-limited node devices. Further, through the power splitting protocol (PSR), the relay divides the received RF signal into two parts according to a certain power split factor, one for energy harvesting and the other for information processing. Besides, this paper presents an optimal power allocation algorithm based on maximum sum rate. Finally, the performance advantages of the proposed scheme are verified by MATLAB simulation.
