ABSTRACT:
A method for eliminating DSL crosstalk is provided. The method includes steps of a coordinated transceiver device notifies an existing online opposite device of a signal sent to a new online opposite device; the coordinated transceiver device receives a calculation result that is obtained by the existing online opposite device based on a detected error signal and the signal sent to the new online opposite device, the coordinated transceiver device updates the coefficient of a vector pre-encoder according to the calculation result. A computer program tangibly embodied on a computer-readable storage medium, computer-readable storage medium, DSL opposite device, DSL coordinated transceiver device and system for eliminating the DSL crosstalk are also provided to implement the method. The provided method may reduce the duration of the crosstalk that the new online opposite device generates on the existing online opposite device, and enable the new online opposite device to join a vector group faster.
