<p>A CDMA receiving apparatus 1 comprises: a path searcher 20 which takes a received data sequence as an input, and which outputs path timing that corresponds to sample timing where a correlation value indicative of correlation between the received data sequence and a reference code sequence reaches a peak, and outputs the correlation value calculated at a sample timing adjacent to the path timing as an adjacent timing correlation value; an interpolation adjuster 40; and a despreader 30 which despreads an output of the interpolation adjuster 40 at the path timing, wherein the interpolation adjuster 40 includes an interpolator 60 for generating an interpolated received data sequence displaced in time by a specified fraction of one sample period with respect to the received data sequence, and outputs the received data sequence or the interpolated received data sequence by switching therebetween based on a result of a comparison between the correlation value calculated at the path timing and the adjacent timing correlation value.</p> |
