Based on the background of Massive MIMO (Multiple-Input Multiple-Output) system, this paper focuses on whether precoding technology can effectively reduce the impact of pilot pollution, and a hybrid precoding scheme based on all-digital precoding and analog beamforming is proposed. The results show that the hardware complexity and cost of the system can be reduced effectively on the premise that the basic performance indexes are close.
