Abstract: In accordance with an embodiment, the method includes detecting an update event whereupon a precoder needs to be updated, sending signal adjustment information to a receiver remotely coupled to a subscriber line out of the plurality of subscriber lines indicative of a signal compensation factor to be applied to a receive communication signal to compensate for a channel bias caused by the scheduled precoder update, and time-coordinating the precoder update with the enforcement of the signal compensation factor at the receiver.

Abstract: In accordance with an embodiment, the vectoring controller is configured to iterate through successive crosstalk acquisition cycles and, within respective ones of the crosstalk acquisition cycles, to configure sequences of crosstalk probing symbols for transmission over the respective communication lines, to receive sequences of error samples as successively measured by respective receivers coupled to the respective communication lines while the sequences of crosstalk probing symbols are being transmitted, and to determine crosstalk estimates between the respective communication lines based on the sequences of error samples. The vectoring controller is further configured to randomize the successive sequences of crosstalk probing symbols used during the successive crosstalk acquisition cycles, and to iteratively configure the vectoring processor based on the successive crosstalk estimates.
