1. A method for estimating channel distortion in a communications channel including an adaptive equalizer, comprising:

  • determining one or more adaptive filter coefficients h1(n) associated with a signal by the adaptive equalizer;

    normalizing the determined one or more adaptive filter coefficients to unit energy; and

    differencing the normalized one or more adaptive filter coefficients with an ideal response h0(n) of the communications channel, the differencing producing an error sequence h2(n).
