A no signal period detecting unit (10) detects a no signal period in which no receiver signal is received. A capture unit (7) captures a synchronous timing of the receiver signal on the basis of a correlation value which is worked out by a delayed correlation computing unit (6). Further, the capture unit (7) cancels the capture of the synchronous timing in the case where this no signal period is detected by the no signal period detecting unit (10). |
