The invention realizes an SVD-MIMO transmission having resistance to the variations in the channel characteristic, which saves the feedback from the receiver to the transmitter. The receiver updates the current one into a new channel matrix H<SUB>new </SUB>every 100 OFDM symbols, and performs the reception processing by updating the current one into a new decoding weight matrix U<SUB>new </SUB>acquired by the singular value decomposition of the channel matrix H<SUB>new</SUB>. On the other hand, the transmitter continues to use the original transmission weight matrix V. The diagonal matrix D is turned into a non-diagonal matrix because of the variations in the channel characteristic, where the elements except for the diagonal elements take the values except for zero. This shows that cross talks are generated at this moment. The receiver acquires the cross talk gains, and cancels the cross talk signals of the reception signal to thereby realize the signal transmission without cross talks in consequence.
