    摘要： The present invention increases the detection accuracy of each of a first to a third steps of cell search to reduce the time required for detecting correct frame boundaries and scramble code. A mobile station inputs a received signal to a matched filter 501 corresponding to a primary synchronization code PSC, and a multi-slot averaging section 502 executes averaging over a plurality of slots in order to reduce the adverse effects of noise and interference. After the averaging over the plurality of slots, a multi-search averaging section 504 further executes averaging over a plurality of searches. Subsequently, a peak detector 503 selects a timing with which an average correlation value is largest, to detect slot boundaries.

    摘要： A synchronization establishing method of a mobile station in a mobile communication system is proposed which can reduce the effect of noise or interference, and achieve higher accuracy than conventional method. To enable the mobile station to detect a signal transmitted from a base station, and to establish synchronization to the signal in a mobile communication system in which a synchronization channel is multiplexed periodically into the downlink signal, the mobile station averages, in phase and in complex numbers, correlation values (201) of the synchronization channel over a plurality of periods, followed by detecting the power of them to carrying out peak detection.
