Abstract
A method for adjusting timing of a secondary system with respect to a reference system is disclosed. The secondary and reference systems include a secondary synchronization signal and a reference synchronization signal, which are used to detect a phase difference between the secondary synchronization signal and the reference synchronization signal. A filtered phase error is generated from the detected phase difference. In addition, a frequency difference is detected between the secondary synchronization signal and the reference synchronization signal, and an instantaneous frequency difference and a filtered frequency error are generated from the detected frequency difference. The filtered phase error and the filtered frequency error are accumulated, and the timing of the secondary system is controlled in accordance with the accumulated filtered phase error, the accumulated filtered frequency error, and the instantaneous frequency difference.
