APPARATUS FOR AND METHOD OF CONTROLLING A FEEDFORWARD FILTER OF AN EQUALIZER.

摘要

A method of controlling a feedforward filter of an equalizer includes the steps of generating a complex representation of an output of the feedforward filter and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a phase error estimate. A phase correction value is generated based on the phase error estimate and used to adjust the phase of the output of the feedforward filter.
