Abstract: To solve a problem in which, in the past, resistance to channel variation is insufficient, and it is necessary to review the selection of combination patterns for each packet, resulting in an enormous amount of computational processing.SOLUTION: A MIMO demodulation method includes the steps of: generating a plurality of combination patterns that selects the same number of received signals as the number of spatial streams from among a plurality of received signals greater than the number of spatial streams; repeating equalization processing in parallel for a plurality of combination patterns and storing a first determination value calculated from the result of the equalization processing for each repetition; and using, as a result of MIMO demodulation, a combination pattern in which a second determination value further calculated from the first determination value is minimized. As a result, it is possible to select a robust combination pattern in which deterioration of demodulation characteristics with respect to time fluctuations of the propagation path is small.SELECTED DRAWING: Figure 3
