Patent ID: 8000301

Claim:
A wireless communication system for carrying out a spatial multiplexing communication between a transmitter having a plurality of antennas, and a receiver having a plurality of antennas, the wireless communication system comprising: channel information matrix acquiring means for acquiring a channel information matrix having transmission functions of the pairs of antennas between the sender side and the receiver side as elements; weighting factor matrix arithmetically operating means for obtaining a weighting factor matrix based on the channel information matrix thus acquired; normalizing means for executing processing for normalizing the weighting factor matrix; detecting means for detecting whether there is presence or absence of an abnormality in the processing executed by the weighting factor matrix arithmetically operating means or the normalizing means; weighting processing means for executing weighting processing based on the weighting factor matrix for each of transmission signals which are transmitted from the transmitter in accordance with a detection result obtained from the detecting means; and transmitting means for transmitting the transmission signals for which the weighting processing means executes the weighting processing from the transmitter to the receiver.
