Abstract

A method for acquiring at least one signal transmitted via an electric conductor, wherein an electric and/or magnetic field of the conductor is acquired at at least two identical or different positions relative to a longitudinal coordinate of the conductor, thus obtaining two measurement signals corresponding to the respective positions, and the signal transmitted via the conductor is inferred from the measurement signals.

Claims

1. A method for acquiring at least one signal transmitted via an electric conductor, comprising:

acquiring at least one of;

i) an electric field, and ii) a magnetic field, of the conductor at at least two positions relative to a longitudinal coordinate of the conductor to obtain two measurement signals corresponding to the respective positions; and

inferring the signal transmitted via the conductor from the measurement signals.

2. The method as recited in claim 1, wherein the at least two positions are identical.

3. The method as recited in claim 1, wherein the at least two positions are different.

4. The method as recited in claim

1, wherein a plurality of signals transmitted via the conductor are inferred from the measurement signals, the plurality of signals including a first signal transmitted in a first direction along a longitudinal coordinate and a second signal transmitted in a second direction opposite the first direction.

5. The method as recited in claim 1, wherein a multidimensional equalization is applied to infer the signal.

6. The method as recited in claim 1, wherein coupling elements are used for the acquisition of the at least one of the electric field, and the magnetic field, of the conductor, the capacitive elements being at least one of:

i) discrete coupling elements, ii) inductive coupling elements, and iii) capacitive coupling elements.

7. A method for analysis of a data communication between at least two data nodes connected to one another via a conductor, the method comprising:

acquiring at least one of;

i) an electric field, and ii) a magnetic field, of the conductor at at least two positions relative to a longitudinal coordinate of the conductor to obtain two measurement signals corresponding to the respective positions; and

inferring the signal transmitted via the conductor from the measurement signals.

8. A device for acquiring at least one signal transmitted via an electric conductor, the device being configured to acquire at least one of:

i) an electric field, and ii) a magnetic field, of the conductor, at at least two positions relative to a longitudinal coordinate of the conductor, to obtain two measurement signals corresponding to the respective positions, and the device being configured to infer, from the measurement signals, the signal transmitted via the conductor.

9. The device as recited in claim 8, wherein the device is configured to infer, from the measurement signals, a plurality of signals transmitted via the conductor, the plurality of signals including a first signal transmitted in a first direction along the longitudinal coordinate and a second signal transmitted in a second direction opposed to the first direction.

10. The device as recited in claim 8, wherein the device is configured to apply a multidimensional equalization, to infer the signal.

11. The device as recited in claim 8, wherein the device has at least two coupling elements for acquiring the at least one of the electric and the magnetic field, of the conductor at the at least two positions of the conductor.

12. The device as recited in claim 11, wherein the coupling elements include at least one of:

i) discrete coupling elements, ii) inductive coupling elements, and iii) capacitive coupling elements.
