TRAINING AND UPDATING FOR MULTIPLE INPUT-OUTPUT WIRELINE COMMUNICATIONS

摘要

The present invention provides a crosstalk mitigator (215) for use in vectoring a digital subscriber line (DSL) system having initial crosstalk interference. In one embodiment, the crosstalk mitigator (215) includes a crosstalk parameter estimation portion (216) configured to determine crosstalk parameters associated with the initial crosstalk interference, and a mitigator initialization portion (217) coupled to the crosstalk parameter estimation portion and configured to train the DSL system to provide a mitigated crosstalk based on the crosstalk parameters prior to a data transmission mode. In an alternative embodiment, the capability to detect a change in the mitigated crosstalk during the data transmission mode and update the crosstalk parameters to rectify the change in the mitigated crosstalk is provided.
