RADIO RECEIVER AND METHOD OF RECEPTION

摘要

Signals received from antennas are input to weighting factor calculation sections 105 and 106. Weighting factor calculation section 105 calculates weighting factors so as to eliminate an interference signal using the antenna reception signals and known signals of a desired signal. Weighting factor calculation section 106 sequentially updates weighting factors so as to minimize the difference between a combined signal and its reference signal using the weighting factors calculated by weighting factor calculation section 105 as the initial values. On the other hand, reception quality measurement section 108 measures the reception quality of the combined signal and outputs the measurement result to weighting factor switching section 107. After receiving the measurement result, weighting factor switching section 107 switches weighting factors to be used for combination at the time the reception quality changes. <IMAGE>
