摘要： A MIMO receiving apparatus that can demodulate a spatially multiplexed signal without using any division operation requiring a large quantity of operation resources. In the MIMO receiving apparatus, stream separation section (105) separates a spatially multiplexed signal into a plurality of streams based on numerator submatrix A. Numerator submatrix A is determined according to channel matrix H and a canceller scheme and corresponds to a numerator of stream separation matrix S that equalizes the phase and amplitude of the spatially multiplexed signal. Denominator part calculation section (108) calculates a denominator (denominator coefficient) of stream separation matrix S and correction section (117) corrects a threshold determined according to a modulation scheme of the spatially multiplexed signal using the denominator (denominator coefficient) of stream separation matrix S. Demapping sections (109-1 to 109-3) calculate likelihoods of the plurality of streams through a threshold decision using the corrected threshold.
