Research on I/Q Unbalanced Channel Reciprocity Calibration Algorithm in Massive MIMO System

摘要：

　　Massive MIMO system uses the transmitter channel state information(CSI)to preprocess the transmitted data,which can effectively reduce the interference and enhance the Massive MIMO system capacity.In the actual transmission process,reciprocity is subject to many factors,resulting in application difficulties.In this paper,we mainly study the influence of RF devices noncardiosis on channel reciprocity of Massive MIMO system.Combined with channel estimation based on pilot signal and FRRH subspace tracking algorithm,this paper proposes a channel reciprocity calibration method for Massive MIMO.Finally,the compensation effect of the compensation algorithm is verified by simulation.
