Title:
RECEIVER
Document Type and Number:
Japanese Patent JP3935120
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a receiver capable of accurately detecting a reference time position for time synchronization without being affected by noise.
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.
