Abstract
A method of timing recovery convergence monitoring in modems using an average phase error signal. The method involves continuously tracking the peak of the average phase error. The average phase error is compared to a dynamic threshold (i.e. a threshold that can change over time based on changes to the detected peak at a given time). Convergence is declared when the average phase error remains less than the threshold over a given length of time (i.e. after processing a prescribed number of consecutive samples).
