The fifth-generation(5G) mobile communications system has got extensive attention and research by enterprises, research institutes and universities of the world at present. Massive MIMO technology is considered to be an important technology in the future 5G. It is mainly used to improve the spectrum efficiency and power efficiency of the communication system. The advantage of massive MIMO and standardized process of MIMO were described and summarized in detail. The main application scenarios were analyzed. From channel measurement and channel modeling, the massive MIMO are introduced, the channel estimation, precoding techniques and signal detection technologys were analyzed. At last, massive MIMO was summarized.
