Abstract: A path search unit (1) detects the correlation between a received signal and a desired signal; (2) based on the correlation value, selects a plurality of paths over which the desired signal arrives; (3) if the difference between the detection time of the desired signal arriving via a path selected this time and the previous-time detection signal is within an allowable range, judges that the path selected this time is identical to a path previously allocated to prescribed finger units, and (4) if a path is identical, causes despreading and delay adjustment processing of the desired signal arriving over the selected path to be executed by the same finger unit as previously. A timing control unit calculates the difference between the detection time this time, over the identical path, and a reference time, and, based on the total of the time differences over the identical path, controls the timing lead/lag.
