基于大规模天线技术的携能传输功率分配研究
RESEARCH ON POWER ALLOCATION BASED ON MASSIVE MIMO AND SWIPT
摘要
Abstract
This paper proposes a power allocation scheme based on the base station (BS) total power minimization criterion for multi-user time-division duplex (TDD) communication system.In the downlink, the scheme equipped with large-scale antenna base station side using zero-forcing pre-coding technology to reduce multi-user interference.To minimize the multi-cell base station to transmit the total power consumption as the optimization target, the scheme takes into account the received signal to noise ratio constraints and energy harvesting requirements.The lower limit of signal to interference plus noise ratio (SINR) was deduced by the Jensen''s inequality, and the wishart matrix in Random matrix theory was used to simplify the lower limit of SINR.The simulation results show that the performance of the proposed scheme is better than that of the traditional average power distribution scheme, which saves a lot of base station power.关键词
