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 at least one analog carrier signal within a wideband signal into at least one digital carrier signal, the at least one analog carrier signal at a respective frequency in the wideband signal; and

translating at least one digital carrier signal to a different frequency.

2. The method of claim 1, further comprising:

filtering the at least one digital carriers signal; and

wherein the translating step translates the at least one filtered digital carrier signal.

3. The method of claim 1, further comprising:

digital processing the at least one translated carrier signal to create a wideband signal.

4. The method of claim 1, further comprising:

converting the at least one digital carrier signal back to at least one analog carrier signals.

5. The method of claim 4, wherein the at least one digital signal is 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 carriers signal; and

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

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

8. The method of claim 1, wherein the at least one carrier 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:

packetizing each of the at least one digital carrier signal into at least one digital packet stream.

10. The method of claim 9, further comprising:

concatenating the at least one digital packet stream.

11. The method of claim 9, further comprising:

sending the at least one digital packet stream to at least one emitter location.

12. The method of claim 9, further comprising:

sending of the at least one digital packet stream to a different emitter location.

13. The method of claim 12, wherein the at least one digital packet stream is translated to a same frequency.

14. A method of translating carriers, comprising:

filtering at least one digital carrier signal within a wideband signal, of the at least one digital carrier signal at a respective frequency in the wideband signal; and

translating the at least one digital carrier signal to a different frequency.

15. The method of claim 14, further comprising:

converting the at least one digital carrier signal to at least one analog carrier signals.

16. The method of claim 15, wherein of the at least one digital signal is converted into at least one analog carrier signal in separate D/A stages.

17. The method of claim 14, further comprising:

digital processing the at least one translated carrier signal to create a wideband signal.

18. The method of claim 15, further comprising:

amplifying and filtering the at least analog carrier signal; and

transmitting the amplified and filtered signal to an endpoint.

19. The method of claim 14, further comprising:

packetizing of the at least one digital carrier signal into at least one digital packet stream.

20. The method of claim 19, further comprising:

concatenating the at least one digital packet stream.

21. The method of claim 19, further comprising:

sending the at least one of digital packet stream to at least one emitter location.

22. The method of claim 19, further comprising:

sending of the at least one digital packet stream to a different emitter location.

23. The method of claim 22, wherein the at least one digital packet stream is translated to a same frequency.
