In a method of tracking on-time errors in a wireless communication system, first and second metrics may be produced from accumulated signal samples of a received data frame, and a sum of, and a difference between, the first and second metrics may be calculated. The calculated difference and sum values may be used to determine an estimated on-time error for the received data frame and a corrected timing error control value to be applied to the on-time error. The accuracy of the estimated on-time error may be evaluated based a signal quality metric to determine whether the corrected timing error control value is to be applied to the estimated on-time error or whether the timing adjustment for the on-time error is to be stopped.
