PROBLEM TO BE SOLVED: To reduce the frequency of synchronization timing changeover control by preventing the accumulation of the errors of phase information set at the time of reception swithcing to keep synchronization so as to reduce the probability of pull out of synchronization. SOLUTION: The system is provided with a cell search module 101 that retrieves a signal sent by a peripheral base station to periodically detect its spread code number, phase information and the intensity of correlation, a reception processing module 104 that simultaneously receives signals from a plurality of base stations by setting the spread code number and the phase information of the cell search module 101 to measure a reception timing, a phase information table processing module 109 that uses the detection result of the cell search module 101 to handle a phase information table 112 managing the information of the reception timing of the signals from a plurality of base stations, and a synchronization timing module 114 that keeps synchronization matched with the reception timing measured by the reception processing module 104. |
