so that the base station can use the same time-frequency resources to serve
Multiple users.In this paper, pilot frequency pollution of large scale MIMO system and its solution are discussed
Channel model, low complexity transmission technology and implementation method are three key technologies.Large scale MIMO compared to existing MIMO systems
The spectrum efficiency, energy efficiency and robust performance of the system can be significantly improved.As the fifth generation mobile communication (5G) has the most potential within the research
