Method and apparatus for analyzing crosstalk between lines

A method for analyzing crosstalk between lines, comprising:

• 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, wherein the lines of which the number is the first number comprise to-be-analyzed lines of which the number is a specific number;
• canceling frequency spectrum notching on a specific frequency band of a to-be-analyzed line whose frequency spectrum notching is not canceled among the to-be-analyzed lines of which the number is the specific number, and collecting a second group of state performance parameters of each line of the lines of which the number is the second number;
• 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;
• and
• determining whether a line whose frequency spectrum notching is not canceled exists in the to-be-analyzed lines of which the number is the specific number, wherein when a line whose frequency spectrum notching is not canceled exists, the method returns to canceling frequency spectrum notching on a specific frequency band of a to-be-analyzed line whose frequency spectrum notching is not canceled among the to-be-analyzed lines of which the number is the specific number, and collecting a second group of state performance parameters of each line of the lines of which the number is the second number;
• and when no line whose frequency spectrum notching is not canceled exists, the method ends.

An apparatus for analyzing crosstalk between lines, comprising:

• a data collector, configured to collect state performance parameters of a line;
• a configurator, configured to perform frequency spectrum notching on a specific frequency band of a line or cancel frequency spectrum notching on the specific frequency band of the line;
• and
• an analysis controller, configured to control an operation by the configurator of frequency spectrum notching or canceling frequency spectrum notching, obtain the state performance parameters of the line from the data collector, and determine crosstalk of a line into another line according to the obtained state performance parameters.
