    摘要： The present invention relates to a method for controlling communications over a plurality of subscriber lines (L1 .. LN), the communications making use of communication signals that are jointly processed through a precoder (120) for crosstalk pre-compensation.
    In accordance with an embodiment of the invention, the method comprises updating one or more coupling coefficients of the precoder for mitigating crosstalk from a subscriber line (Li) into one or more victim lines, sending signal adjustment information to a receiver (xTU-Ri) remotely coupled to the subscriber line indicative of a signal compensation factor (γi) to be applied to a receive communication signal to compensate for a channel equalization bias caused by crosstalk pre-compensation signals superimposed over the one or more victim lines and corresponding to the respective one or more updated coupling coefficients of the precoder, and time-coordinating the precoder update with the enforcement of the signal compensation factor at the receiver.
    The present invention also relates to corresponding first and second communication controllers forming part of an access node and a subscriber device respectively.
