Abstract

See full text

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 includes a training signal generation unit that generates a known signal predetermined, a CP addition unit that adds a CP to each symbol of a transmission signal including the known signal, a weight generation unit that multiplies a channel matrix estimated based on the known signal by the reception apparatus by a pseudo-inverse matrix obtained by a predetermined number of iterative calculations to generate a transmission weight that is diagonalizable, and a transmission beam formation unit that uses the transmission weight to form a transmission beam for the transmission signal where the CP is added.
