Title:
VECTOR CALCULATION METHOD AND APPARATUS FOR REMOVING FAR-END CROSSTALK OF SUBSCRIBER LINE
Document Type and Number:
WIPO Patent Application WO/2016/101420
Kind Code:
A1
Abstract:
A vector calculation method and apparatus for removing far-end crosstalk of a subscriber line relate to the technical field of accessing networks. The method comprises: dividing N numbers of user ports into M numbers of classifications according to the size of the value of far-end crosstalk of every user port; respectively extracting one user port from every classification of the user ports, respectively calculating the values of far-end crosstalk of the extracted M numbers of user ports, respectively setting the same as the values of far-end crosstalk of the rest of the user ports having the same classification of the user port as the user port; according to the values of far-end crosstalk of the M classifications of user ports, composing a crosstalk calculation matrix of the entire system, and conducting vector calculation for removing the far-end crosstalk. Also disclosed in the embodiment of the present invention is a vector calculation apparatus for removing the far-end crosstalk of a subscriber line. The technical solution of the present application makes a progress in the terms of reducing time for improving the system to conduct vector calculation, reducing time for conducting vector calculation, and improving user experience effect.
