Patent ID: 8644127

Claim:
A method of performing per-tone mitigation, comprising: receiving an input signal of an identified crosstalk disturber; determining one or more instantaneous characteristics of the input signal, wherein the characteristics comprise at least one of an amplitude level of the input signal and an energy level of the input signal; determining whether to process the input signal of the identified crosstalk disturber for mitigation according to the one or more instantaneous characteristics of the input signal; and based on the determination of whether to process the input signal for mitigation, either processing the input signal for mitigation or allowing the identified crosstalk disturber to be unmitigated, thereby performing partial crosstalk mitigation, wherein the per-tone mitigation comprises performing partial far-end crosstalk (FEXT) mitigation, and wherein determining instantaneous characteristics of the input signal according to the amplitude level comprises comparing the amplitude level to a predetermined threshold, and wherein FEXT cancellation is bypassed for constellation points associated with the input signal located within a decision boundary defined by the predetermined threshold.
