Abstract

With the development of wireless transmission technologies, the technique that combine wireless power transmission and information transmission have become the trends and one of the research hotspots, namely simultaneous wireless information and power transmission (SWIPT). The SWIPT system is of great significance for alleviating the power shortage of communication nodes and devices. However, most academic research focuses on SWIPT systems in cellular network scenarios. In this paper, the application of the SWIPT system is discussed for satellite ground integrated network such as the disaster area emergency network based on the LEO satellite. The different characteristics of independent information transmission and power transmission are analyzed, and some basic methods for the simultaneous transmission of wireless power and information are described. The system model of wireless power and information simultaneous transmission for satellite ground network is introduced. The function of the power splitting ratio and the distance from the satellite to the ground node is deduced, and the power splitting design method is to optimize for maximum communication rate and the node’s harvesting power. The optimal selection parameters of the power splitting ratio on the different distance between the satellite and the ground node are solved. By analyzing the model simulation data, the maximum communication rate and maximum power efficiency are given at different distances.
