Method of generating circularly polarised signals from a polarisation controller of a ground station

A method for generating a circular polarisation signal from at least two transponders of a satellite able to process linearly polarised signals includes: a transmission of at least two linearly polarised signal components so as to produce a circularly polarised signal by at least two transponders of a satellite; processing signals by the two transponders of the satellite to produce a circular polarisation of the signals transmitted by the satellite; ground receiving by at least one circularly polarised antenna; measuring a physical parameter from the received signals, and determining a correction parameter to be applied to the generation of the components of linearly polarised signals; generating a compensation of the components of linearly polarised signals transmitted to the satellite.. . ...

Radio communications system and method with increased transmission capacity based on frequency twisted waves

A method of implementing orbital angular momentum (oam) for radio communications in general and lte in particular. Common prior art so far recreate the vorticity (axial rotation of the poynting vector) by using ring-shaped antenna arrays. ... Eutelsat S A

Exploitation of frequency twisted waves in wireless communication systems to increase transmission capacity thereof

A system combining ofdm standard modulation with a superimposition of orbital angular momentum modes, each oam modes consisting in an overlapping decimated iffts with the main mode standard ofdm signal, orthogonality of the oam modes is assessed, a frame structure embodying both main mode ofdm samples and overlapping oam modes is proposed.. . ...

Method for establishing radiofrequency links in a telecommunication network with an optimised ground gateway network

A method for establishing radiofrequency links via a satellite having several spots between a gateway and a service area comprising a plurality of elementary covering zones, designated cells, each cell being associated to a spot and including a plurality of terrestrial terminals, a forward link between the gateway towards the plurality of terrestrial terminals including a first step in which the gateway emits a first analog radiofrequency signal towards the satellite, with a first spectral efficiency; a second step in which a payload of the satellite receives the first analog radiofrequency signal; a third step in which the payload processes the first analog radiofrequency signal, and a fourth step in which the payload emits a plurality of second analog radiofrequency signals towards the cells with a second spectral efficiency, the first spectral efficiency being greater than the second spectral efficiency.. . ...

Radio communications system and method with increased transmission capacity

A radio communications method includes carrying out, by a transmitter: providing a digital time signal carrying digital symbols to be transmitted; and transmitting a radio frequency signal carrying the digital time signal. The method further includes carrying out, by a receiver: receiving the radio frequency signal transmitted by the transmitter; processing the received radio frequency signal to obtain a corresponding incoming digital signal; and extracting, from the incoming digital signal, the digital symbols carried by the incoming digital signal. ...
