Abstract

A description is given of a device and a method for the noise shaping of a transmission signal such as are employed, for example, in a data transmission system.

Claims (27)

1. A method for the noise shaping of a transmission signal, comprising:

generating a first signal with a first frequency spectrum;

providing a power information signal, which represents information about a signal level of a transmission signal;

providing a sequence signal according to a desired spectral mask;

noise shaping the first signal dependent on the power information signal and the sequence signal to form a second signal, the noise shaping including shifting components of the first signal from the carrier frequency of the first signal into a sideband of the carrier frequency, wherein the second signal complies with the desired spectral mask; and

providing the second signal as transmission signal.

2. The method as claimed in claim 1 , comprising:

generating the sequence signal from a random number sequence.

3. The method as claimed in claim 2 , wherein the random number sequence represents white noise.

4. The method as claimed in claim 2 , wherein the random number sequence has a memory.

5. The method as claimed in claim 2 , further comprising adding the sequence signal to the first signal.

6. The method as claimed in claim 2 , comprising:

generating the power information signal dependent on an additional item of information to be transmitted.

7. The method as claimed in claim 2 , wherein the noise shaping is performed by a delta-sigma modulator.

8. A device for generating a transmission signal comprising:

a signal generator for generating a first signal with a first frequency spectrum, wherein the first frequency spectrum includes a carrier frequency;

a power control unit for providing a power information signal, which represents a signal level of the transmission signal;

a sequence generator for providing a sequence signal according to a desired spectral mask;

a first signal shaper configured to noise shape the first signal dependent on the power information signal and the sequence signal to form a second signal, which shifts power components of the first signal from the carrier frequency into a sideband of the carrier frequency at least one frequency range away from the carrier frequency; and

a signal output for providing the second signal as transmission signal.

9. The device as claimed in claim 8 , comprising:

an adder configured to add the sequence signal to the first signal.

10. The device as claimed in claim 8 , wherein the first signal shaper includes a delta-sigma modulator.

11. The device as claimed in claim 8 , wherein the sequence generator comprises a random number generator.

12. The device as claimed in claim 11 , wherein the random number generator generates pseudo-random numbers.

13. The device as claimed in claim 11 , wherein the sequence generator further comprises a scaling unit configured to scale numbers generated by the random number generator.

14. The device as claimed in claim 11 , wherein the sequence generator further includes a circuit for impressing a memory term on the sequence signal.
