  • Method and apparatus for analyzing crosstalk between lines
    Patent number: 9014291
    Abstract: Embodiments of the present invention provide a method and an apparatus for analyzing crosstalk between lines, where the method includes: performing frequency spectrum notching on a specific frequency band of lines of which the number is a first number among multiple lines, collecting a first group of state performance parameters of each line of lines of which the number is a second number among the multiple lines; canceling frequency spectrum notching on the specific frequency band of the to-be-analyzed line, collecting a second group of state performance parameters of each line of the lines of which the number is the second number; and determining, according to the first and second groups of state performance parameters, crosstalk of each line of the lines of which the number is the second number into the to-be-analyzed line on the specific frequency band.
