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 Hnew every 100 OFDM symbols, and performs the reception processing by updating the current one into a new decoding weight matrix Unew acquired by the singular value decomposition of the channel matrix Hnew. 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.

In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station. With performing such processing, a system can be formed based on minimum level of transmission and reception operation when transmission and reception data does not exist in each communication station in the network, and also a data transfer can be performed with latency as small as possible in a minimum necessary level of transmission and reception operation by making a transition of a transmission and reception state in accordance with a fluctuating volume of transmission and reception data.
