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.

摘要： The present invention relates to a vectoring controller (130) for determination of a vectoring matrix (P, Q) that is used for joint processing of Discrete Multi-Tone DMT communication signals to be transmitted over, or received from, a plurality of subscriber lines (L 1 to L N ).
In accordance with an embodiment of the invention, the vectoring controller is configured to determine first coefficient values ( P ki , Q ki ) for the vectoring matrix at a first tone (k i ) by means of a first number of iterations (n 1 ) through an iterative update algorithm and based on a first channel matrix estimate (H ki ) at the first tone, and to determine second coefficient values ( P ki+1 , Q ki+1 ) for the vectoring matrix at a second neighboring tone (k i+1 ) by means of a second number of iterations (n 2 ) through the iterative update algorithm and based on a second channel matrix estimate ( H ki+1 ) at the second tone. The vectoring controller is further configured to start with the so-determined first coefficient values as initial values for the respective second coefficient values in the iterative update algorithm. The second number of iterations is lower than or equal to the first number of iterations.
The present invention also relates to a method for determining a vectoring matrix (P, Q).

摘要： The present invention relates to a vectoring controller (130) for configuring a vectoring processor (120) that jointly processes DMT communication signals (u 1 ..u N ; y 1 ..y N ) to be transmitted over, or received from, a plurality of N subscriber lines (L 1 ..L N ) according to a vectoring matrix (P k ; Q k ). In accordance with an embodiment of the invention, the vectoring controller is adapted, for given ones (k) of a plurality of tones, to enable the given tone for direct data communication over a first set of N-M k targeted lines (A k ) out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of M k supporting lines (B k ) out of the plurality of N subscriber lines, M k denoting a non-null positive integer. The vectoring controller is further adapted to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of M k supporting lines for further enhancement of data signal gains at the given tone over the first set of N-M k targeted lines. The present invention also relates to a method for configuring a vectoring processor.
