Abstract:
1. A wireless communication method in which a first wireless communication apparatus performs data communication with a second wireless communication apparatus by using a plurality of transmission channels formed by spatial multiplexing, the method comprising the steps of: determining an error rate of a communication between the first wireless communication apparatus and the second wireless communication apparatus; executing a calibration process of forming the plurality of transmission channels between the first wireless communication apparatus and the second wireless communication apparatus if it is determined that the determined error rate is higher than a predetermined error rate, and not executing the calibration process of forming the plurality of transmission channels between the first wireless communication apparatus and the second wireless communication apparatus if it is determined that the determined error rate is lower than the predetermined error rate, wherein the calibration process comprises determining an eigenvector for the first wireless communication apparatus based on transmission channels information, and calculating weights based on the determined eigenvector for weighting signals that are transmitted from the first wireless communication apparatus.
