Abstract:
1. A reception data synchronizing apparatus for a synchronization to be obtained between reception data having a plurality of synchronism patterns and expectation data as an expected value of the reception data, comprising: a phase difference recording means for recording a time difference between a second synchronism pattern detecting timing at which a second of the plurality of synchronism patterns is detected in the reception data and a first synchronism pattern detecting timing, as an initial one at which a first of the plurality of synchronism patterns is initially detected in the reception data; a timing generating means for generating a timing for decision; and a collation and synchronism decision means for collating the reception data with the expectation data to decide whether or not the reception data is consistent in phase with the expectation data according to the timing for decision, wherein the timing for decision is the first synchronism pattern detecting timing before the collation and synchronism decision means collates the reception data with the expectation data, and wherein the timing for decision is a timing obtained by shifting the first synchronism pattern detecting timing by the time difference recorded in the phase difference recording means, when the collation and synchronism decision means gives a decision for inconsistency in phase.
