毫米波大规模MIMO系统波束选择方案的设计
Design of a beam selection scheme for millimeter wave massive MIMO systems
摘要
Abstract
To solve the high energy consumption problem of millimeter wave massive MIMO systems using traditional full digital precoding caused by too many required radio frequency chains, a beam selection scheme based on lens was proposed.The proposed beam selection scheme divides all the users into the two groups of interference-users as well as noninterference-users, and then, for noninterference-users, uses the maximum power criterion to conduct beam selection, while for interference users, uses the low complexity incremental algorithm to select appropriate beams to maximize the system sum-rate.The simulation results show that the proposed beam selection scheme can nearly reach the full digital precoding scheme's system sum-rate on the basis of effectively reducing the number of required RF chains and the computation complexity.关键词
