摘　　要：mMIMO毫米波高速通信系统是未来人类社会构建更好通信体验的关键基础.受限于集成电路制造过程中存在的较大随机偏差和失配,弱鲁棒性问题成为制约高速通信系统规模化推广应用的主要瓶颈.本文深入挖掘影响mMIMO毫米波高速通信系统性能的关键因素,并对收发链路I/Q失配校准、数/模混合波束合成收发链路多通道幅相失配校准、发射阵列非线性失真补偿等算法进行归纳和总结,为未来构建沉浸化、智慧化、全域化的高速通信场景提供坚实技术支撑.mMIMO millimeter-wave high-speed communication system is the key foundation for the better communication experience in future human society.Limited by the large random deviation and mismatch in the manufacturing process of integrated circuits,weak robustness has become the main bottleneck restricting the large-scale promotion and application of high-speed communication systems.This paper deeply explores the key factors affecting the performance of mMIMO millimeter-wave high-speed communication system,and summarizes the algorithms such as I/Q mismatch calibration of transceiver link,multi-channel amplitude and phase mismatch calibration of digital/analog hybrid beamforming transceiver link,and nonlinear distortion compensation of transmit array,so as to provide technical support for the construction of immersive,intelligent and global high-speed communication scenarios in the future.
