    Abstract: A transmitter of a binary data stream comprises: a serial/parallel converter to split the binary data stream into m different parallel bit streams, each bit stream having a rate D/m which is m times lower than the initial rate D; m first encoding modules to error-correcting encode each bit stream individually; a time-interleaver to intermix the information bits originating from different encoded bit streams; an encoder to error-correcting encode the m interleaved bit streams into p bit streams; p electro-optical modulators to modulate each of the p bit streams delivered by the interleaver by means of p optical carriers of different wavelengths; and a wavelength-division multiplexer to combine the les p optical carriers into a single optical signal.

    Abstract: A satellite telecommunications system has a global coverage area and a plurality of user terminals distributed in the global coverage area. The global coverage area is covered by a first set of spots which form a regular cellular mesh, and by at least a second set of local spots, irregularly distributed and superimposed geographically on spots of the first set. The spots of the first set of spots have allocated channels with the same frequency capacity, the same channel being re-used by a plurality of different spots, and the local spots of the second set of spots have a special allocated channel having an increased frequency capacity.

    Abstract: An intermediate network for a radiocommunication system, the intermediate network includes one or more stations located on high-altitude platforms in order to connect a set of remote base stations to one or more ground stations. The high-altitude platforms are networked by way of communication links, for example high-speed free-space optical links. The invention also proposes to connect remote base stations positioned outside of the area of coverage of the stations located on high-altitude platforms via for example microwave-link relay stations or base stations at the edge of the area of coverage.

    Abstract: A method is provided for dynamically allocating the radio resources of a satellite and a very high throughput satellite system configured to implement this method. The method of allocation is executed by a piece of ground equipment called a Radio Resource Manager. The method of allocation according to the invention, allocates dynamically in time frequency resources to each spot of the multibeam coverage in accord with the conditions of propagation of the radio signals (in particular the attenuations due to bad weather) prevailing in the spots, with the current and future spot data traffic profile, with the level of interference generated in the neighbouring beams. The method preferentially applies in respect of downgoing forward links, that is to say from the satellite to the user terminals.
