Patent ID: 8737510

Claim:
A wireless communication system comprising: a transmitting apparatus; and a receiving apparatus including N antennas (where N is an integer, N≧2) configured to perform multiple input multiple output wireless communication with the transmitting apparatus, and a processor configured to calculate each of inverse matrixes of each of channel matrixes of each of combinations of L antennas (where L is an integer, 1≦L<N) selected among the N antennas, by calculating at least one inverse matrix of the inverse matrixes based on at least one channel matrix of the channel matrixes, and by calculating remaining inverse matrix other than the at least one inverse matrix of the inverse matrixes based on the at least one inverse matrix, and to select an antenna combination among the combinations of L antennas, the combination whose reference value satisfies a specified condition, the reference value being calculated based on an inverse matrix of the inverse matrixes which corresponds to the combination, the specified condition being for determining whether L antennas indicated by the combination fits a successive interference cancellation process or not.
