The present invention includes path delay difference comparator 14 for receiving path delay amounts tau 1 to tau K detected from a reception signal and extracting each pair of paths satisfying first condition ( ¾ tau i - tau j¾ </= tau th), de-spreaders 111 to 11K for performing de-spreading according to the path delay amounts, estimator 121 to 12K for estimating an SIR value every path, estimators 131 to 13K for estimating the carrier phase every path, phase difference comparator 15 for comparing the carrier phases &thetas; 1 to &thetas; k of the paths of each pair satisfying the first condition and extracting each pair of paths satisfying second condition (¾&thetas;i - &thetas;j¾ </= &thetas; th), and comparator 16 for selecting one path having larger SIR from the paths of each pair extracted and using the SIR value of the selected path for SIR combining. <IMAGE> |
