大规模MIMO技术通过增加基站天线数大幅提高系统频谱效率和能量效率,是未来5G移动通信网络的关键技术。文中在大规模MIMO系统模型下,对多种信号检测算法进行仿真,研究其性能,对大规模MIMO技术的实际应用具有一定的指导意义。对仿真结果的分析表明,当基站天线数远远大于用户数时,简单的线性信号检测算法也能达到很好的系统性能。

Massive MIMO, is known as large-scale antenna system which is the key technology in the fifth generation（SG） of mobile network, and brings huge improvements in spectral efficiency and energy effi- ciency by using a large excess of antennas of base station. This paper simulates several signal detection algorithms and analyzes their performances on the massive MIMO system model with some degree of guid- ing significance for the practical application of massive MIMO technology. The simulation result shows that when the number of base station antennas is larger than the number of users, the simple signal detection algorithms can achieve good system performance.
