Abstract
The fifth generation mobile communication network (5G) has received extensive attention and a lot of research from global enterprises, research institutes and universities. massive MIMO technology is considered as an important technology in future 5G, mainly used to improve the spectrum utilization and channel capacity of communication system. This paper analyses in detail the standardization process of MIMO technology and the technical advantages of massive MIMO. It mainly applies scenarios, and then introduces from the perspective of channel measurement and channel modelling. It analyses the channel estimation technology, pre-coding technology and signal detection technology in massive MIMO system and makes a summary finally.
