Patent ID: 7826568

Claim:
A method of cancellation of far-end crosstalk (FEXT) from one or more adjacent wire pairs, said method comprising the steps of: performing feed forward equalization (FFE) on a signal received over a wire pair so as to generate a desired equalization signal therefrom; performing linear FEXT equalization on signals received from said adjacent wire pairs taken before feed forward equalization (FFE) in their respective receiver circuits so as to generate FEXT error signals therefrom, wherein said step of performing linear FEXT equalization comprises the step of filtering corresponding receive signals using an N×N matrix W(D) comprising filter coefficients representing the frequency transformation between said FEXT error signals and the signals received from each adjacent wire pair, wherein N is a positive integer greater than zero; and subtracting said FEXT error signals from said desired equalization signal to generate a FEXT compensated signal therefrom.
