Abstract

In order to send electromagnetic signals received on one or more first frequency bands, the method applies a transformation to the signals, by performing the following actions: selecting first frequency sub-bands, forming a first set of frequency sub-bands of the first frequency band(s); using organization rules to associate one or more second sets of frequency sub-bands, forming one or more second frequency bands, with each first frequency sub-band of the first set; and using optimization rules to determine frequency translations to transpose the signals received in the first frequency sub-bands into signals sent in the second frequency band(s).

Claims

1. A method for transmitting electromagnetic signals received in one or more first frequency bands, comprising:

selecting first frequency sub-bands as a first set of frequency sub-bands of the first frequency band(s);

in accordance with organizational rules, associating with each of the first frequency sub-bands of the first set, one or more second sets of frequency sub-bands of one or more second frequency bands; and

determining, for each of the first frequency sub-bands selected, frequency translations for transposing the signals received in the first frequency sub-bands to signals transmitted in the second frequency band(s) in order to defragment the first set of frequency sub-bands in the second frequency band(s) by reducing width of the second frequency band(s).

2. The method according to claim 1, including selecting only the first frequency sub-bands in which electromagnetic signals considered wanted are received.

3. The method according to claim 1, wherein the organizational rules include rules of associating a second frequency sub-band with a segment covering all or part of a first frequency sub-band.

4. The method according to claim 1, where in the organizational rules include rules for building the one or more second sets of frequency sub-bands adjacent to at least one other frequency sub-band of the second set.

5. The method according to claim 1, used in a cellular communication network.

6. The method according to claim 1, wherein the signals are transmitted over a wireless connection.

7. The method according to claim 1, wherein the signals are transmitted via an optical fiber.

8. A device for transmitting electromagnetic signals received in one or more first frequency bands, comprising:

a first frequency converter at an input of a filter that is driven to select a first sub-band of a first frequency band by transposing the signals received in the first sub-band to a pass band of the filter associated with the first frequency converter; and

a second frequency converter at the input of the filter that is driven to apply a frequency translation to defragment a first frequency set in a second frequency set in view of reducing the width of a second frequency band, by transposing the signals going through the pass band of the filter, in a second sub-band of the second frequency band associated with the selected first sub-band.

9. The device according to claim 8, wherein the first frequency converter is controlled by an input setpoint generator to intersect with the pass band of the filter associated with a first frequency sub-band in which wanted signals are received.

10. The device according to claim 8, wherein the filter is controlled by a pass band adapter to superimpose the pass band of the filter on a first frequency sub-band segment.

11. The device according to claim 8, wherein the second frequency converter is controlled by an output setpoint generator to release the second sub-band obtained at the filter, adjacent at least one other frequency sub-band of the second frequency set.
