PROBLEM TO BE SOLVED: To provide a channel information prediction system which is used in a multi-antenna transmission system for calculating a predicted filter coefficient to be used for suppression of interference components included in a received radio signal to predict channel information, and which icludes further improved prediction performance of the channel information. SOLUTION: The channel information prediction system executes first prediction for predicting the channel information in future transmission of the radio signal using a first prediction filter coefficient calculated using a low wavelet element in a transform MIMO CSI, and suppresses components of the wavelet included in the low wavelet element. The channel information prediction system executes second prediction for predicting the channel information in future transmission of the radio signal using the low wavelet components in which the components of the wavelet are suppressed.
