Abstract

FD-SWIPT two-way relay is used to provide cell coverage in mobile cellular networks and improve the throughput and energy efficiency of the system. To address the problem in FD-SWIPT bidirectional relay research, an efficient and throughput maximization scheme based on joint optimization antenna selection and beamforming in the FD-SWIPT bidirectional relay system is proposed in this study. First, a sub-optimal antenna grouping algorithm with low complexity is presented. The strategy of antenna grouping is used at the relay receiver to transmit the received signal with great channel CSI to the destination node, and then the remaining signal is used for energy harvest. Second, the beamforming scheme is designed at the relay transmitter, and the maximum generalized eigenvalue method is used to optimize the beamforming vector and enhance the signal-to-interference-plus-noise ratio of the system. The simulation results show that the proposed joint optimization scheme can effectively improve the throughput and energy efficiency of the system, and the antenna selection scheme plays an important role in the system.
