An SVD unit 19 performs singular value decomposition on each channel estimation value. An orthogonality determination unit 20 determines (recognizes) whether orthogonality of a plurality of eigenpaths is maintained or collapsed based on information indicating quality of a channel between a transmission apparatus and a reception apparatus. A reception scheme estimation unit 22 estimates a reception scheme to separate eigenpaths of a reception unit 2 based on information indicating quality of a channel in each eigenpath. A transmission adaptive control unit 23 performs predetermined control of a transmission apparatus 1 at transmission based on the reception scheme of the reception apparatus estimated by the reception scheme estimation unit 22 and a result of determination (recognition) by the orthogonality determination unit 20.
