Method, apparatus, and system for processing signals based on twisted pair

摘要

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, an apparatus, and a system for processing signals based on a twisted pair. The method for processing signals based on a twisted pair includes: determining a signal processing manner; performing, according to the signal processing manner, digital processing on signals of the extended channels that are to be sent to convert the signals of the extended channels into common mode signals of each twisted pair; and sending the converted common mode signals of the each twisted pair to corresponding twisted pairs for transmission.

1. A method for processing signals based on a twisted pair, comprising:
determining a signal processing manner of M extended channels which are generated on the basis of N twisted pairs, wherein 1≦M≦N−1, and wherein the signal processing manner comprises acquiring signals of an extended channel by making a difference between common mode signals of any two of the N twisted pairs, or by making a difference between a sum of common mode signals of at least two of the N twisted pairs and common mode signals of any another of the N twisted pairs, or by making a difference between a sum of common mode signals of at least two of the N twisted pairs and a sum of common mode signals of at least another two of the N twisted pairs; performing vector precoding processing on the common mode signals of the twisted pairs and differential mode signals of the twisted pairs, wherein a vector precoding matrix used by the vector precoding processing is a matrix of N+M rows and N+M columns on subcarriers; performing, according to all signal processing manners of M extended channels, digital processing on signals of the extended channels and converting the signals of the extended channels into common mode signals of the N twisted pairs; and sending the converted common mode signals of the twisted pairs to corresponding twisted pairs for transmission.
