Systems and methods for comparing communication links

Abstract

A method for comparing communication links in a communication network includes (a) obtaining first raw equalizer coefficients in a frequency domain, the first raw equalizer coefficients corresponding to a first communication link, (b) obtaining second raw equalizer coefficients in the frequency domain, the second raw equalizer coefficients corresponding to a second communication link, (c) removing time delay from the first raw equalizer coefficients to generate first corrected equalizer coefficients, (d) removing time delay from the second raw equalizer coefficients to generate second corrected equalizer coefficients, and (e) comparing the first corrected equalizer coefficients to the second corrected equalizer coefficients to determine a relationship between the first and second communication links.
