PROBLEM TO BE SOLVED: To provide a CDMA receiver that can detect fluctuations for preventing deteriorated performance, even when fluctuations occur with reception timing which is more rapid than the averaged time of a delay profile, such as an incoming MS(mobile station) tracking. SOLUTION: A search circuit 105 measures a finer assignment path location from a received signal. Correlation units 113, 115, 116 conduct correlation processing between the received signal and a spread code at the finger assignment path position and positions shifted, before and after the path position by a unit shift. Then the shift between the reception timing and the finger assignment path position is detected, on the basis of the result of correlation processing and employing the detected result can properly execute control, such as transmission power control where countermeasures to rapid fluctuations in the reception timing are requirements. |
