METHOD, DEVICE AND SYSTEM FOR GROUPING LINE PAIRS

摘要

A method, device and system for grouping line pairs are provided by the embodiment of the present invention, which relates to the field of communications and resolves the problem that due to the large amount of the line pairs in the large scale Vectored-DSL system, obtaining, through the channel training, the crosstalk cancellation coefficient matrix demands a very high capability of a system, such as the computing capability, the storage capability, and even impacts the user experience. The technical solution provided by the present invention comprises: obtaining the crosstalk impact data between the line pairs in the Vectored-DSL system (101); the line pairs, between which the crosstalk impact can not be ignored, are divided into a vector group according to the crosstalk impact data between the line pairs and the set threshold value (102). The method and device for grouping the line pairs provided by the embodiment of the present invention can be applied to the large scale Vectored-DSL.
