DYNAMIC DIGITAL COMMUNICATION SYSTEM CONTROL

摘要

Control of a digital communication system having a plurality of communication lines on which signals are transmitted and received is implemented using a variety of methods and systems. According to one embodiment of the present invention, a method is implemented where the signals are affected by interference during transmission and each of the communication lines has at least one transmitter and at least one receiver. A model is created of the interference characteristics due to the signals carried on the communication lines. Interference characteristics for a line are determined based on the model and actual signals carried on other communication lines different from the line for which the characteristics are being determined. Actual interference is compensated for on the communication line using the determined interference characteristics.

1. A method of vectored reception in a Digital Subscriber Line (DSL) system using Discrete Multi-tone communications over a plurality of communications lines, each of the plurality of communication lines having at least one transmitter and at least one receiver, and wherein cross-talk interference between the plurality of communication lines occurs during reception, the method comprising:
receiving signals within a plurality of tones from at least one of the plurality of communication lines, determining parameters of a canceller block using a communication adaptation unit and line and signal characteristics of the plurality of communication lines, and eliminating or reducing, using the canceller block and the determined parameters, crosstalk within each tone of the plurality of tones of the signals received from at least one of the plurality of communication lines, and receiving the signals within each tone from the canceller block.
