Patent ID: 8331867

Claim:
A wireless communication system for performing wireless communication between a transmission apparatus and a reception apparatus via a plurality of eigenmodes comprising: a channel estimation unit for calculating a channel estimation value between the transmission apparatus and the reception apparatus; a channel prediction unit for calculating a channel prediction value of the transmission apparatus at transmission based on the channel estimation value calculated by the channel estimation unit; an eigenvalue calculation unit for calculating an eigenvalue in a predetermined period based on the channel prediction value calculated by the channel prediction unit; an eigenmode quality calculation unit for calculating a value indicating quality of the eigenmode in the predetermined period based on the eigenvalue calculated by the eigenvalue calculation unit; and a control unit for controlling predetermined processing of the transmission apparatus at transmission based on the value calculated by the eigenmode quality calculation unit, wherein the control unit controls such that the value indicating the quality is smaller for a higher eigenmode in accordance with frequency of channel variation based on the channel estimation value and/or channel prediction value calculated.
