<p>A receiving apparatus includes a converting unit that multiplies first and second reception signal points for the respective first and second reception signals by a matrix and outputs resulting converted first and second reception signal points; a number-of-candidates determining unit that determines a number of candidates for at least first transmission-signal candidate points, based on a reception quality for the first and second reception signals; and an estimating unit that selects, based on the converted first and second reception signal points, the first transmission-signal candidate points and second transmission-signal candidate points, the number of first transmission-signal candidate points corresponding to the determined number of candidates, and that estimates, as the first and second transmission signals, the first and second transmission-signal candidate points with which distances between the selected first and second transmission-signal candidate points and the corresponding converted first and second reception signal points are smallest.</p> |
