Abstract:
A perch channel reception device of a mobile radio communication terminal according to CDMA (Code Division Multiple Access) for successively receiving perch channels transmitted by base stations around the mobile radio communication terminal, said perch channel reception device comprising:a receiving circuit receiving a modulated signal from a plurality of base stations, wherein: on each completion of perch channel reception of a base station, a time difference between a real scrambling timing of a currently-received base station and a scrambling timing which has been used for executing a perch channel reception of the currently-received base station is detected; and a timing correction is calculated as an accumulation of the time difference thereby correcting a scrambling timing of the next base station which has been detected based on a delay profile, and perch channel reception of the next base station is executed using the corrected scrambling timing of the next base station.
