Reception data synchronizing apparatus and method, and recording medium with recorded reception data synchronizing program

Abstract

A synchronism pattern detecting timing recorder () records a synchronism pattern detecting timing at which a synchronism pattern is detected in reception data, a synchronism decider () collates the reception data with reference data to decide whether or not the reception data is consistent in phase with the reference data, and a timing generator () operates, when the synchronism decider () gives a decision for inconsistency in phase, for a match between the synchronism pattern detecting timing recorded in the synchronism pattern detecting timing recorder (), as a subsequent one, and a timing of a synchronism pattern of the expectation data, and the subsequent synchronism pattern detecting timing in record is used to render the phases consistent, allowing for a rapid synchronization to be obtained, without the need of waiting a detection of synchronism pattern, even with an inconsistency in phase due to a false synchronism pattern.
