Provided is a channel information prediction system which uses a low ray element in a transformation MIMO CSI to calculate a first prediction filter coefficient. By using the obtained first prediction filter coefficient, the system executes a first prediction for predicting channel information upon a radio signal transmission in the future and suppresses a component of the ray contained in the low ray element. By using the low ray component in which the ray component is suppressed, the system executes a second prediction for predicting channel information upon a radio signal transmission in the future.
