PROBLEM TO BE SOLVED: To compress the amount of information to be fed back from a receiver side to a transmitter side, when SVD-MIMO transmission is performed. SOLUTION: In SVD-MIMO system communication using singular value decomposition, a reference symbol is transmitted from the receiver side to the transmitter side, in place of feeding V back acquired by singular value decomposition of a channel information matrix acquired on the receiver side, a channel information matrix is acquired on the transmitter side, and singular value decomposition is performed on the transmitter side too. When the transmitting vector V necessary when transmission is performed is formed, inequality between a forward channel matrix and a backward channel matrix is corrected by correcting errors of transmitting and receiving analog elements on the transmitter side and on the receiver side.
