Abstract:
A method for remote crosstalk cancellation, includes: 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; synthesizing, at the first transmitting end, a first signal to be transmitted over the first line and the filtered crosstalk source signals; transmitting the synthesized signal from the first transmitting end to the first receiving end over the first line; receiving, at the first transmitting end, a noise statistic related value fed back from the first receiving end; and adjusting, at the transmitting end, the values of the filtering parameters according to the noise statistic related value. A corresponding device and a signal processing system for remote crosstalk cancellation are provided.
