Patent ID: 8295369

Claim:
A far-end crosstalk canceling method, comprising: filtering, at a first transmitting end which is connected to a first receiving end over a first line, crosstalk source signals according to values of filtering parameters, wherein the crosstalk source signals are related to signals to be transmitted over second lines, each of the second lines having a second transmitting end connected to a second receiving end; synthesizing, at the first transmitting end, a first signal to be transmitted over the first line with the filtered crosstalk source signals; transmitting the synthesized first signal from the transmitting end to the first receiving end over the first line; receiving, at the transmitting end, a noise statistic related value fed back from the first receiving end, wherein the noise statistic related value reflects a numeric value of a signal-to-noise ratio of the synthesized first signal received by the first receiving end; adjusting, at the transmitting end, the values of the filtering parameters according to the noise statistic related value, wherein the adjusted values of the filtering parameters are used in filtering the crosstalk source signals.
