PROBLEM TO BE SOLVED: To obtain a wireless communication apparatus for achieving further throughput improvement in a multiuser MIMO system. SOLUTION: The apparatus includes: a singular value decomposition part (16) for performing a singular value decomposition in a first channel matrix showing a propagation path situation with a first receiving terminal; a cancel signal generation part (19) for generating a interference cancel signal based on first transmitting data to a first receiving terminal, a first right singular matrix output by the singular value decomposition part (16), and a second channel matrix showing the propagation path situation with a second receiving terminal; a singular value deposition part (17) for performing the singular value deposition of the channel matrix generated based on the second channel matrix and the first right singular matrix, and addition parts (20 to 24) for adding the interference cancel signal to multiplication results of a second right singular matrix output by the singular value deposition part (17) and second transmitting data to a second receiving terminal.
