Abstract

A plurality of carrier signals in a wide band signal is converted into a plurality of digital carrier signals. Each of the plurality of carrier signals is at a respective frequency in the wide band signal. At least one of the plurality of digital carrier signals is translated to a different frequency.

Claims

1. A method of translating carriers, comprising:

converting a plurality of analog carrier signals within a wideband signal into a plurality of digital carrier signals, each of the analog carrier signals at a respective frequency in the wideband signal;

packetizing the plurality of digital carrier signals into a plurality of digital packet streams;

sending each of the plurality of digital packet streams to separate and distinct emitter locations; and

translating each of the plurality of digital packet streams to a different frequency at each of the emitter locations, to adjust a position of the digital packet stream within the wideband signal.

2. The method of claim 1, further comprising:

filtering at least one of the plurality of digital carriers signals; and

wherein the packetizing step packetizes the at least one filtered digital carrier signal.

3. The method of claim 1, further comprising:

digital processing the plurality of digital packet streams to create a wideband signal.

4. The method of claim 1, further comprising:

converting the plurality of digital packet streams back to at least one analog carrier signal.

5. The method of claim 4, wherein the plurality of digital packet streams are converted into the at least one analog carrier signal in a separate D/A stage.

6. The method of claim 4, further comprising:

amplifying and filtering the at least one converted analog carrier signal; and

transmitting the at least one amplified and filtered signal to an endpoint.

7. The method of claim 1, wherein at least one of the carrier signals is a carrier in a code division multiple access (CDMA) network.

8. The method of claim 1, wherein at least one of the carrier signals is a carrier of one of a wideband code division multiple access (WCDMA), a Global System for Mobile Communications (GSM), and tones in a Worldwide Interoperability for Microwave Access (WiMax) systems.

9. The method of claim 1, further comprising:

concatenating each of the plurality of digital packet streams.

10. The method of claim 1, wherein the translating adjusts at least one of the plurality of digital packet streams relative to other ones of the plurality of digital packet streams within the wideband signal.

11. A method of translating carriers, comprising:

converting a plurality of analog carrier signals within a wideband signal into a plurality of digital carrier signals, each of the analog carrier signals at a respective frequency in the wideband signal;

filtering at least one of the plurality of digital carrier signals;

packetizing the plurality of digital carrier signals into a plurality of digital packet streams;

sending each of the plurality of digital packet streams to separate and distinct emitter locations; and

translating each of the plurality of digital packet streams to a different frequency at each of the emitter locations, to adjust a position of the digital packet stream within the wideband signal.

12. The method of claim 11, further comprising:

converting the plurality of digital packet streams back into at least one analog carrier signal in a separate D/A stage.

13. The method of claim 11, further comprising:

digital processing the plurality of digital packet streams to create a wideband signal.

14. The method of claim 11, further comprising:

amplifying and filtering at least one converted analog carrier signal; and

transmitting the amplified and filtered signal to an endpoint.

15. The method of claim 11, further comprising:

concatenating each of the plurality of digital packet streams.

16. The method of claim 11, wherein the translating adjusts at least one of the plurality of digital packet streams relative to other ones of the plurality of digital packet streams within the wideband signal.
