Adjusted transmission in XDSL

摘要

Method and transmitting node for adjusting transmission over xDSL lines connected to the transmitting node. The method involves transmitting (1006) a first signal A1 on a first line (304), and transmitting (1008) a second signal A2 on a second line (306), the second signal A2 being related to the first signal A1. The method further involves adjusting (1010) the transmission of the second signal A2 on the second line (306), such that a contribution from the second signal A2 interferes constructively with a signal A1′ at the second end (304:2) of the first line (304), where the signal A1′ represents the signal A1 having propagated through the first line.

1. A method, in a transmitting node connected to a respective first end of a first digital subscriber line and a second digital subscriber line, a second end of the first digital subscriber line being connected to a first receiving node, the method comprising:
transmitting a first signal (A1) on the first digital subscriber line; transmitting a second signal (A2) on the second digital subscriber line, the second signal being related to the first signal; adjusting the transmitting of the second signal on the second digital subscriber line such that a contribution from the second signal interferes constructively with a signal (A1′) at the second end of the first digital subscriber line, where the signal A1′ represents the first signal A1 having propagated through the first digital subscriber line.
