Document Type and Number:
Japanese Patent JP3448008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately detect a CP signal sent on the way of an initializing signal without misdetection.
SOLUTION: A difference between current sampling data and sampling data of one preceding data unit is calculated, each difference calculated by each sampling is integrated by tracing back by number of samples of CP signal inserted to the initializing signal in the past, and the position of the CP signal is confirmed on the basis of the sample number where the integrated value denotes a minimum value.
