Abstract:
A carrier phase and symbol timing recovery circuit and method may be used for robust synchronization in a broadcasting ATSC receiving system. Carrier phase and symbol timing offsets may be simultaneously adjusted by using redundancy information contained in an ATSC signal spectrum. A desired sampling time instant and carrier phase offset for synchronization may be simultaneously obtained due to correlation between carrier phase and symbol timing detectors.
