摘　　要：研究了Massive MIMO中的预编码算法,对ZF、MMSE和SVD 3种线性预编码算法进行了公式推导和仿真对比,并对5G中的上下行参考信号及其功能进行了简要介绍。随后对5G中的波束赋形方案进行了研究,包括5G下行参考信号工作原理及流程,并对单流、双流和多流3种波束赋形方案的性能进行了仿真分析。The precoding algorithm in Massive MIMO is studied.The three linear precoding algorithms ZF,MMSE and SVD are deduced and simulated,and the uplink and downlink reference signals and their functions in 5G are briefly introduced.Then the beam-forming scheme in 5G is studied,including the working principle and flow of 5G downlink reference signal,and the perfor-mance of three beamforming schemes,single stream,dual stream and multi stream,is simulated and analyzed.
