Abstract: A vectoring controller is configured to determine first coefficient values for a vectoring matrix at a first tone based on a first number of iterations through an iterative update algorithm and a first channel matrix estimate at the first tone, and to determine second coefficient values for the vectoring matrix at a second neighboring tone based on a second number of iterations through the iterative update algorithm and a second channel matrix estimate at the second tone. The vectoring controller is configured to start with the 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.

Abstract: In accordance with an embodiment the method includes temporarily configuring the vector processor with a new set of vectoring coefficients during one or more selected symbol positions; restoring the current set of vectoring coefficients outside the one or more selected symbol positions; obtaining at least one error measure over respectively at least one line of the group of vectored lines during the one or more selected symbol positions; and determining a suitability indication for the new set of vectoring coefficients based on the obtained at least one error measure.

Abstract: A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of N−Mk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of N−Mk targeted lines.

Abstract: The present invention relates to a communication controller (131; 132) and method for controlling communications between an access node (101; 102) and a plurality of remote communication units (211; 212) coupled to the access node via at least one wired transmission medium (20; 40). At least one communication unit (111, 211; 112, 212) of the access node and of the plurality of remote communication units is configured to operate in full-duplex mode according to a first full-duplex communication profile (OP1) when using a first subset of transmission resources (TSSET1; TONESET1) selected from a whole set of transmission resources available for communication over the at least one transmission medium, and according to a second full-duplex communication profile (OP2) when using a second non-overlapping subset of transmission resources (TSSET2; TONESET2) selected from the whole set of transmission resources. The first full-duplex communication profile includes first downstream and upstream transmit power profiles (PSDDS1, PSDUS1) to achieve first aggregate downstream and upstream data rates (DSMAX1, USMIN1; DSMAX2, USMIN2) over the at least one transmission medium, and the second full-duplex communication profile includes second downstream and upstream transmit power profiles (PSDDS2, PSDUS2) to achieve second aggregate downstream and upstream data rates (USMAX1, DSMIN1; USMAX2, DSMIN2) over the at least one transmission medium distinct from the respective first aggregate downstream and upstream data rates. The present invention also relates to a so-configured full-duplex communication unit.
