ABSTRACT:
A method and system for improved phase tracking in communication systems is disclosed. In one embodiment, a method, comprises identifying a slow-time varying phase drift on a link by counting long term beats; calibrating an interpolator with the phase drift; predicting a future phase drift; and updating the interpolator periodically with the future phase drift prediction.
