To have the efficiency of power save control enhanced by reducing a period for the reception operation during the standby state.

A spread code which multiplies a Walsh code by a PN code is given to multipliers 11, 12 which is included in a DLL of a finger 2. Furthermore, integration damping filters 14, 15 set an integration period for one symbol period. Prescribed PN codes included in a spread code given to multipliers 10, 11, 12 are selected among many searching PN codes, which are shifted by a half tip each around a prescribed central phase as a center. While the processing above is executed, an output with a maximum absolute value is detected from all the outputs of respective 1st to 3rd integration means of plural fingers and a phase of the searching PN code given to the integration means is selected so as to be the center phase through the control of the searching PN generating means.
