摘要
Massive MIMO技术可以通过增加天线数增加系统容量,并利用不同用户间信道的近似正交性降低用户间干扰,实现多用户空分复用。首先总结了Massive MIMO技术的Rel-13版本标准化内容,分析了面向5G系统的Massive MIMO技术的主要研究内容,最后结合中国联通现状,分析了该技术的演进方向。
Massive MIMO technology can adopt increasing number of antennas to improve the system capacity and reduce inter-user interference based on approximate orthogonal channels between different users, which realize multi-user multiplexing in the space domain. It firstly summarizes the standardization contents of Rel-13 FD-MIMO specification, analyzes the key research contents of massive MIMQ. Finally, it analyzes the evolution direction of Massive MIMO in combination with the current situation of China Unicorn.
