FAR-END CROSSTALK CANCELING METHOD AND DEVICE

摘要

A method for remote crosstalk cancellation, includes: the combination transmitting signal is performed a pre-coding of crosstalk cancellation in the manner of self-adapting filtering, the self-adapting changes of the values of filtering parameters are guided correctly with the influence of the crosstalk component in the received signals which is reflected indirectly by relevant values of the noise statistic reported by the receiver. A corresponding device for remote crosstalk cancellation is provided.

1. A method for reducing far-end crosstalk in a digital line system, wherein the system comprises a first line and second lines, the method comprises:
receiving a noise related value fed back from a first receiving end to a first transmitting end over the first line; pre-coding, a first signal and crosstalk source signals according to values of filtering parameters to form a synthesized signal corresponding to the first line; wherein the crosstalk source signals are related to second signals over the second lines, and the values of the filtering parameters are acquired according to the noise related value; wherein the first signal is to be transmitted over the first line from the first transmitting end to the first receiving end, and the second signals are to be transmitted from a second transmitting end to a second receiving end over each of the second lines; and transmitting the synthesized signal from the first transmitting end to the first receiving end over the first line.
