Patent ID: 8831114

Claim:
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.
