Abstract

this paper discusses the application of SWIPT(simultaneous wireless information and power transmission) system in space system. The scheme of simultaneous wireless information and power transmission based on OFDM is elaborated in detail. The scheme of simultaneous wireless information and power transmission receiving based on time switching mode is adopted. The influence of allocation factor in time switching on system performance is analyzed, the optimal allocation factor of time switching is solved. The optimal switching time scheme improves the overall throughput performance of the system, and carries out numerical analysis.
