In a spread spectrum receiver, when a preliminarily set integration period for integrating a correlated power of a received signal is significantly offset with respect to a fading period, accurate follow-up of a path becomes difficult to lower synchronization acquisition ability. To avoid this, in a fading period computing unit, an offset of the transmission power is obtained from a transmission power control information extracted by a decoder, correlated power calculation is performed for deriving the fading period on the basis of the result of the correlated power calculation. According to this fading period, the integrated period is determined to accurately perform synchronization acquisition by performing integration of the correlated power depending upon the fading period.
