RECEIVER

PROBLEM TO BE SOLVED: To provide a receiver for enabling signal separation by suppressing interference at each reception antenna without using equalization processing by a MMSE method.SOLUTION: A receiver comprises: timing indication means for indicating a non-signal period in which no signal of a radio communication system owning the receiver is transmitted; noise estimation means for measuring reception power of a reception signal in the non-signal period for each reception antenna, and outputting the reception power as an interference power value; weighting processing means for calculating a weighting coefficient, for each reception antenna, which decreases with increasing in the interference power value and increases with decreasing in the interference power value, from the interference power value of each reception antenna output by the noise estimation means, multiplying the reception signal of each reception antenna by a corresponding weight coefficient, and outputting signals corresponding to the number of transmission antennas; and demodulation/decoding means for demodulating/decoding each output of the weighting processing means, separating/recovering signals differing from each other transmitted from the plurality of transmission antennas, and outputting the signals.
