Title:
A METHOD, DEVICE, AND SYSTEM FOR CANCELING CROSSTALK SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/085455
Kind Code:
A1
Abstract:
The present application relates to the field of communications, and provides a method, device, and system for canceling a crosstalk signal. The method is applied to a twisted pair communication system. The twisted pair communication system comprises a first line and at least one second line, the first line is connected to a first network node and a first user node, and the at least one second line is separately connected to at least one second network node and at least one second user node. The first user node is at least connected to a first CPE and a second CPE. When the first CPE communicates with the first network node, a first crosstalk coefficient between the first line and the at least one second line is obtained according to an error signal fed back by the first CPE; when the second CPE communicates with the first network node, a signal to be sent to the second CPE is pre-coded according to the first crosstalk coefficient between the first line and the at least one second line and according to a first update factor. According to the present application, the consumption of storage space can be reduced.
