Abstract

The invention provides a channel matrix processing method and apparatus. The method comprises the following steps: receiving signaling sent by a maximal ratio transmission MRT controller, wherein thesignaling is used for indicating an identifier of a line pair that exits or enters a predetermined group and the identifier of the predetermined group; obtaining a precoding coefficient matrix according to the identifier of the line pair and the identifier of the predetermined group; and performing diagonalization processing on an MRT channel matrix through the precoding coefficient matrix, wherein the MRT channel matrix is generated by an MRT precoder according to an MRT precoding matrix and a remote crosstalk FEXT channel matrix, and the number of rows and the number of columns of the MRT channel matrix are the number of activated customer premise equipment CPE. By adoption of the channel matrix processing method and apparatus provided by the invention, the problem that the crosstalk between groups cannot be eliminated when the line pairs "enter" or "leave" the groups in the related art is solved, and the effect of eliminating the crosstalk is achieved.

Description

technical field [0001] The present invention relates to the technical field of Digital Subscriber Line (DSL for short), in particular to a channel matrix processing method and device. Background technique [0002] The Maximal Ratio Transmission (MRT for short) technology was proposed by British Telecom in the ITU-T proposal in September 2016. It is a method for effectively utilizing idle line pairs in the vector group to obtain space diversity gain. The principle of MRT is to convert the strong crosstalk between channels into a received Signal-Noise Ratio (SNR) for a specified customer premise equipment (CPE) through precoding diversity at the transmitter. Gain, so as to achieve the purpose of increasing the rate boosting. [0003] Assuming that there are N twisted pairs and K active users (number of CPEs) in a vector group, figure 1 is a schematic diagram of simplified use cases of vector groups in related technologies, such as figure 1 As shown, N=8 and K=2 in the vecto...
