Oversampling CDMA receiver

In a CDMA receiver, an A/D converter (10, 310, 410) over-samples an analog reception baseband signal with a sampling clock a frequency of which is 2 times higher than a chip clock, and converts it into a digital reception baseband signal. A correlator (20, 320, 420) obtains a correlation value between the digital reception baseband signal and a pilot spreading code which is synchronous with a reception timing. A phase difference detecting unit (30, 330, 430) obtains a phase difference between the digital reception baseband signal and the reception timing based on the correlation value. A timing controlling unit (40, 340, 440) changes the reception timing in such a manner as to eliminate the phase difference obtained by the phase difference detecting unit (30, 330, 430).
