Abstract
A synchronizing apparatus comprises a normal lock synchronization detecting unit for detecting synchronization by detecting from demodulated data a synchronization pattern in a normal lock state, and a pseudo lock synchronization detecting unit for detecting synchronization by detecting from the demodulated data a synchronization pattern in a pseudo lock state.
Claims16
A synchronizing apparatus for detecting synchronization by detecting from demodulated data a synchronization pattern in a normal lock state and/or a synchronization pattern in a pseudo lock state.
A synchronizing apparatus, which is provided on a receiving side of a system for modulating/demodulating and transmitting data having a configuration where a fixed data pattern succeeds immediately after a synchronization pattern, comprising:
- a synchronization pattern detecting unit for detecting a synchronization pattern from demodulated data;
- a data pattern obtaining unit for obtaining a data pattern that succeeds immediately after the synchronization pattern detected by said synchronization pattern detecting unit;
- and
- a determining unit for determining whether synchronization is taken either in a normal lock state or in a pseudo lock state according to the data pattern obtained by said data pattern obtaining unit.
A synchronizing method, comprising:
- detecting synchronization by detecting from demodulated data a synchronization pattern in a normal lock state or a synchronization pattern in a pseudo lock state;
- and
- determining whether the synchronization is detected either in the normal lock state or in the pseudo lock state according to a detection result of the synchronization.
