<P>PROBLEM TO BE SOLVED: To provide a receiver capable of accurately detecting a reference time position for time synchronization without being affected by noise. <P>SOLUTION: A moving average calculation section 23 averages correlation values each obtained from a received signal calculated by a correlation calculation section 21 and a known signal from a notice signal generating section 22, a peak detection section 24 detects a peak value and a peak position of the moving average values in each interval obtained by sectioning repetitive notice signals included in the received signals by each repetitive period, and a synchronization discrimination section 25 discriminates the peak value and a reference time position for the time synchronization by using the peak position. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
