Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] Since the digital subscriber line (Digital Subscriber Line, DSL) copper wire access solution can make full use of the telephone subscriber loops that have been laid in large numbers, and reduce the network access investment cost, therefore, the use of copper wires to provide higher-speed Internet access has received great attention. Us...

Abstract

Embodiments of the present invention provide a signal processing method, device, and system, the method comprising: the sending end multiplies the signal processed by the lattice-based protocol by the power control factor corresponding to the port sending the signal; the sending end The signal multiplied by the corresponding power control factor is multiplied by the linear precoding matrix to obtain the output signal of each port after the linear precoding process. Using the signal processing method and device provided in the embodiments of the present invention, the far-end crosstalk generated between the multiple signals accessed by the DSLAM can be eliminated through the linear coding control matrix, and the corresponding power control factor can be used to Limiting the power amplification effect of the linear precoding matrix on the signals of the ports before the lattice-based reduction processing, so that the transmitting end can allocate corresponding power control factors to the ports according to the system configuration, thereby improving the signal Noise ratio and signal transmission rate.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a signal processing method, device, and system. Background technique [0002] Since the digital subscriber line (Digital Subscriber Line, DSL) copper wire access solution can make full use of the telephone subscriber loops that have been laid in large numbers, and reduce the network access investment cost, therefore, the use of copper wires to provide higher-speed Internet access has received great attention. Users welcome. In order to meet users' increasing demand for access network speed, the International Telecommunication Union has formulated the next-generation copper bandwidth access technology standard G.fast. Since the frequency band used by G.fast is getting wider and wider, the far-end crosstalk generated between multiple signals accessed by a digital subscriber line access multiplexer (Digital Subscriber Line Access Multiplexer, DSLAM) seriously...
