Claim 1:
2. A wireless communication method for performing transmission by SC-MIMO between a transmission apparatus including a plurality of antennas and a reception apparatus including the number of antennas different from the number of antennas of the transmission apparatus, the wireless communication method comprising:
generating, by the transmission apparatus, a known signal predetermined;
adding, by the transmission apparatus, a CP to at least one symbol of a transmission signal including the known signal;
removing, by the reception apparatus, the CP added to a reception signal;
estimating, by the reception apparatus, a channel matrix based on the known signal;
multiplying, by the transmission apparatus or the reception apparatus, the channel matrix by a pseudo-inverse matrix obtained by a predetermined number of iterative calculations to generate a transmission weight that is diagonalizable;
using, by the transmission apparatus, the transmission weight to form a transmission beam for the transmission signal where the CP is added; and
performing, by the reception apparatus, equalization processing on the reception signal where the CP is removed.
