Abstract
A radio communication device that, even if it is interfered by a radio transmission station other than a radio transmission station with which it intends to communicate, estimates a signal transmitted from the intended radio transmission station by taking into account the influence of the interference, by obtaining an estimator of 's' that denotes a column vector representing a signal transmitted from the radio transmission station, in accordance with a following expression: s=RssH(HRssH+Ruu)r, where 'Rss' denotes a covariance matrix of the column vector “s”, “r” denotes a column vector representing the signal received by the signal receiving unit, “H” denotes a matrix being the numerical sequence calculated by the first calculating unit, “Ruu” denotes a covariance matrix being the numerical sequence calculated by the second calculating unit, “” denotes a complex conjugate transposition, and “” denotes an inverse matrix.
