Abstract
A method and a device are provided for crosstalk evaluation of a channel, wherein the channel is represented and/or modeled by a multiple-input-multiple-output (MIMO) system connecting a first network component with at least one second network component. The MIMO system contains first coefficients associated with transmission lines that are in particular associated with crosstalk. The crosstalk contains a near-end crosstalk (NEXT) portion and a far-end crosstalk (FEXT) portion. The first network component sends a signal to one second network component; the far-end crosstalk portion and the near end crosstalk portion are evaluated.

A method for crosstalk evaluation of a channel, the channel being represented by a multiple-input-multiple-output (MIMO) system connecting a first network component with at least one second network component, the MIMO system containing first coefficients associated with transmission lines and second coefficients associated with crosstalk, wherein the crosstalk contains a far-end crosstalk portion and a near-end crosstalk portion, the method comprises the steps of:
- sending, via the first network component, a signal of a predetermined power density to one of second network components;
- and
- evaluating the far-end crosstalk portion and the near end crosstalk portion.
A device for crosstalk evaluation, comprising:
- a processor unit programmed to:
- send, via a first network component, a signal of a predetermined power density to one of second network components;
- and
- evaluate a far-end crosstalk portion and a near end crosstalk portion.
A communication system, comprising:
- a device for crosstalk evaluation having a processor unit programmed to:
- send, via a first network component, a signal of a predetermined power density to one of second network components;
- and
- evaluate a far-end crosstalk portion and a near end crosstalk portion.
