A wireless communication apparatus includes: a channel information acquiring unit that, acquires a transmitted signal channel matrix that is channel information as a transmitted signal of a pre-interference-removal transmitted signal group and an interference signal channel matrix that is channel information as an interference signal of the non-interference-removed transmitted signal group; an interference signal calculating unit that generates an interference signal group at the time of reception by the non-interference-removed transmitted signal group with respect to the pre-interference-removal transmitted signal group, based on the pre-interference-removal transmitted signal group, the non-interference-removed transmitted signal group, the transmitted signal channel matrix, and the interference signal channel matrix; a subtracting unit that subtracts the interference signal group from the pre-interference-removal transmitted signal group to generate a post-interference-removal transmitted signal group; and a transmission antenna group that transmits the post-interference-removal transmitted signal group and the non-interference-removed transmitted signal group from mutually different transmission antennas.
