Abstract
With the rapid development and wide application of the wireless communication network, the communication network based on the simultaneous wireless information and power transfer (SWIPT) technology has attracted more and more extensive research. This technology solves the problem of frequent charging or replacement of the device battery very well, has greatly extended the working hours of the device, and can be adapted to some special communication environments such as high temperature and high pressure. This paper studies the effect of the energy allocation in multi-user SWIPT relaying system on the information rate. Thereinto, the relay uses the energy harvested in the energy harvesting mode to amplify and forward the information of the users. The total information rate maximization model is proposed and the corresponding energy allocation scheme is derived. The simulation results show that the proposed energy allocation scheme can maximize the total information rate of all users.
