Abstract:
Disclosed is a method for minimizing feedback overhead in a multi-input multi-output (MIMO) communication method using multiple transmission and reception antennas. In particular, a method for minimizing feedback overhead in a multi-input multi-output (MIMO) communication system by using spatial channel covariance, as explicit channel status information (CSI) feedback method is disclosed.
