Far-end crosstalk canceling method and device
Abstract:
A method for reducing far-end crosstalk in an xDSL system is provided. The method includes transmitting, by a first DSL transceiver over a first line to a second DSL transceiver, a noise statistic related value that reflects a signal-to-noise ratio of the first line and receiving, by the first DSL transceiver over the first line from the second DSL transceiver, a synthesized signal pre-coded on the second DSL transceiver using filtering parameters associated with the noise statistic related value. The method further includes transmitting, by the first DSL transceiver over the first line to the second DSL transceiver in response to the reception of the synthesized signal, an updated noise statistic related value. A corresponding device for remote crosstalk cancellation is also provided.
