Abstract
Methods and systems for phase correction include determining a phase error direction and generating a prediction for the phase error based on a sigma-delta error. It is determined whether the prediction agrees with the determined phase error direction. If the prediction does not agree, a phase correction is adjusted in accordance with the predicted phase error.
