Abstract
A wireless communication method MIMO communication using a wireless communication apparatus having N antennas includes performing first inverse-matrix determining processing which determines, using a channel matrix for a first antenna selected from the N antennas, a first inverse matrix of the channel matrix; performing second inverse-matrix determining processing which determines, with respect to a (n+1)th antenna selected from antennas other than the first to nth antennas already selected, a second inverse matrix of a channel matrix for a group of the first to (n+1)th antennas, by performing computation using a value from one of the first inverse matrix and the second inverse matrix, and performing communication using, from a plurality of combinations of the L antennas selected from the N antennas, a combination of L antennas with which an inverse matrix value determined in the first and second inverse-matrix determining processing satisfies an antenna selection criterion.
