| 1. A method of equalizing digital data signals, comprising the steps of:
demodulating and decoding an input signal having input data to produce a data output;
remodulating the data output to produce a pseudo-training sequence including an idealized input signal;
generating equalizer parameters from the pseudo-training sequence; and
equalizing the input signal according to the equalizer parameters.
