Abstract
Soft decision sections () provisionally decide each modulated signal () separated using an inverse matrix calculation of a channel fluctuation matrix at separation section (). Signal point reduction sections () reduce candidate signal points of a multiplexed modulated signal using the provisional decision results (). Soft decision sections () make a correct decision using the reduced candidate signal points and obtain received data (RA, RB) of each modulated signal. This allows received data RA, RB with a good error rate characteristic to be obtained with a relatively small number of calculations without reducing data transmission efficiency.
