A switch controlling section 204 controls a switching device 205 and a switching device 211 such that mode information, which shows that a current state of an apparatus is an initial synchronous mode, which is a power-on time, or a standby mode, which is a cell moving time, is input, correlation processing is performed by a matched filter 209 in the initial synchronous mode, and correlation processing is performed by a sliding correlator 210 in the standby mode. This makes it possible for a CDMA radio communication system to establish initial synchronization at high speed and to improve a reduction in current consumption. <IMAGE> |
