IRS辅助UM-MIMO系统的联合主被动波束成形设计
Joint Active and Passive Beamforming for IRS-Assisted UM-MIMO System
摘要
Abstract
In this paper,the downlink transmission problem of intelligent reflecting surface(IRS)assisted ultra-massive MIMO system is studied.It focuses on the joint optimization design problem of 1 bit precoding and IRS phase shifting when the base station is equipped with 1 bit digital-to-analog converters.Due to the coupling of the joint optimization variables,an optimization algorithm based on constructive interference is proposed.By alternating the optimization of the transmitted signal vector and IRS phase shift,the suboptimal solution to the joint optimization problem is finally obtained.Numerical results show that the proposed algorithm can achieve good performance.关键词
