Patent ID: 8265123

Claim:
A CDMA receiving apparatus for demodulating a received signal by applying despreading thereto using a code sequence identical to a spreading code sequence, comprising: a path searcher 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 said received data sequence and a reference code sequence reaches a peak, and outputs said correlation value calculated at a sample timing adjacent to said path timing as an adjacent timing correlation value; an interpolation adjuster which includes an interpolator for generating an interpolating data sequence which is a data sequence displaced in time by a specified fraction of one sample period with respect to said received data sequence, and which outputs said received data sequence or said interpolating data sequence by switching therebetween based on a result of a comparison between said correlation value calculated at said path timing and said adjacent timing correlation value; and a despreader which despreads an output of said interpolation adjuster at said path timing, wherein said interpolation adjuster performs control for switching between said received data sequence and said interpolating data sequence only for a path timing where said path timing correlation value becomes maximum from among a plurality of path timings detected on a multipath channel by said path searcher.
