Claim 2:
3. A transmission apparatus including the number of antennas different from a reception apparatus and performing transmission by SC-MIMO to and from the reception apparatus, the transmission apparatus comprising:
a training signal generation unit configured to generate a known signal predetermined;
a CP addition unit configured to add a CP to at least one symbol of a transmission signal including the known signal;
a weight generation unit configured to multiply, by a pseudo-inverse matrix obtained by a predetermined number of iterative calculations, a channel matrix estimated based on the known signal by the reception apparatus to generate a transmission weight that is diagonalizable; and
a transmission beam formation unit configured to use the transmission weight to form a transmission beam for the transmission signal where the CP is added.
