Abstract
A method for use in data communications equipment for improving convergence of a hybrid decision feedback apparatus including an adaptive feed-forward equalizer and an adaptive decision feedback equalizer. An independent error predictor component is used for better convergence and then is eliminated by converting, using z-transformations, the adaptive feed forward equalizer and adaptive decision feedback equalizer to an equivalent feed forward equalizer and an equivalent decision feedback equalizer, respectively, in which the error predictor is embedded or incorporated therein. The smaller system with a reduced number of FFE-DFE coefficients has a faster convergence rate.
