摘要:
 针对5G核心技术—大规模MIMO系统的预编码技术，文中重点阐述了ZF预编码技术、MMSE预编码技术、BD预编码技术，以及脏纸预编码技术、矢量预编技术、tHP预编码技术，并通过仿真比较线性预编码的优劣，得出同一信噪比情况下MMSE预编码技术性能明显优于ZF和BD预编码技术。最后提出新的多小区MIMO预编码技术，同时考虑小区内和小区间的干扰，在计算量和误差方面做了权衡，对信道状态信息进行估计，并与ZF预编码进行仿真比较，结果表明容量有了明显提高。
Abstract:
 In terms of the pre-coding technology in massive Multiple Input Multiple Output ( MIMO) system which is a core technology of the fifth-generation mobile communication,focus on ZF pre-coding,MMSE pre-coding,BD pre-coding,DPC,THP,vector pre-cod-ing and analyze linear pre-coding using MATLAB which proves that MMSE pre-coding is superior to ZF and BD pre-coding under the same SNR. Finally,a new pre-coding for the multi-cell MIMO which takes the global CSI into account is mentioned. It strikes a balance between computational complexity and error,estimating the channel state information and is proved to be effective compared with the ZF pre-coding.
