A method and apparatus for estimating Doppler channel in an Orthogonal Frequency-Division Multiplexor. The method includes selecting a continuation pilot, generating a channel estimation, filtering the continual pilot with at least one channel estimator, computing the error between the channel estimation and the filtered channel estimates, averaging the error across continual pilot carriers and over time, estimating noise variance, corrects average error utilizing the estimated noise variance to generate an estimate of the overall channel estimator error, and setting the filter cutoff to minimum estimation error.
