Abstract
A method and apparatus for estimating sample timing error in discrete multitone modulated signals. An unprocessed measured tone. The phase of the selected measured tone is adjusted using an average phase error. A normalized phase error for the selected measured tone is estimated. The average phase error is updated with the estimated phase error.
