Abstract
A method for equalizer correction in a communication network includes (a) obtaining raw equalizer coefficients in a frequency domain, (b) removing time delay from the raw equalizer coefficients to generate corrected equalizer coefficients in a time domain such that a direct current (DC) corrected equalizer coefficient of the corrected equalizer coefficients has a phase of zero, and (c) converting the corrected equalizer coefficients from the time domain to the frequency domain.
