PROBLEM TO BE SOLVED: To unnecessitate a searcher circuit to be operated only at the time of hand-off and to reduce the circuit scale of a device by selectively inputting a received signal from each sector to the searcher circuit and performing hand- off between sectors. SOLUTION: Synchronizing position signals S12A, B obtained by tracking operation are inputted to a control circuit 131 based on searcher select signals S13A, B by searcher input selector circuits 111, 112, four optional tracking position signals 13G to J are selected and formed from among synchronizing positions to be specified by the signals S12A, B. Finger input select signals S13C to F showing the received signal corresponding to each tracking signal are simultaneously formed, the received signal S10A or 13B is selected based on the finger input select signals, given to corresponding finger circuits 151 to 154, synchronous connection and demodulation for a signal S10A or S13B are performed in position relation instructed by tracking position signals S13G or S13B, demodulation signals S15A to D are provided to be combiner 161, and a demodulation signal S17 is obtained by coupling them by each of the finger input selector circuits 141 to 144.
