基于混合波束赋形的室内毫米波MIMO系统性能分析
Performance Analysis of the Hybrid Beamforming Based Indoor Millimeter Wave MIMO System
摘要
Abstract
Hybrid beamforming increases data rate through digital beamforming in baseband and analog beamforming in radio frequency.In order to analyze the capacity of indoor millimeter wave multiple input multiple output (MIMO) system based on hybrid beamforming,we investigate the zero force (ZF) receiver,the minimum mean square error (MMSE) receiver,and the matched filter (MF) receiver to obtain the data rate of the system under the optimal codebook-based beam selection in different circumstances.Simulation results show that whether the line-of-sight path is blocked,both the MMSE receiver and the ZF receiver achieve the performance which is close to the capacity under high total transmit power;under low total transmit power,the performance of the MMSE receiver is slightly better than the ZF receiver.However,the MF receiver shows poor performance.The system could adopt suitable receiver according to total transmit power and the complexity of receiver.The practical indoor wireless personal area networks (WPAN) could achieve high data rate short-distance wireless communications by applying the system we investigated in this paper.关键词
