Patent ID: 8045446

Claim:
A method for eliminating crosstalk between digital subscriber lines (DSLs), comprising: notifying, by a coordinated transceiver device, an existing online opposite device of a signal sent to a new online opposite device, the notifying comprising sending, by the coordinated transceiver device, an initial value of a sequence generator that is used to generate the signal and a time when the signal is sent, to the existing online opposite device, wherein sequence generators with the same structure are respectively configured in the coordinated transceiver device and the existing online opposite device; and obtaining, by the existing online opposite device, the signal according to the configured sequence generator, the initial value of the sequence generator, and the time when the signal is sent; receiving, by the coordinated transceiver device, a result of a calculation that is obtained by the existing online opposite device, wherein the calculation is performed based on a detected error signal and the signal sent to the new online opposite device; and updating, by the coordinated transceiver device, a coefficient of a vector pre-encoder based on the calculation result.
