摘要： A method for establishing radiofrequency links via a telecommunication satellite having several spots, designated a multispot satellite, between at least one terrestrial station and a service area composed of a plurality of elementary covering zones, designated cells, each cell comprising a plurality of terrestrial terminals is disclosed. This type of satellite allows the use of several spots of antennae on board the satellite to cover contiguous geographical zones or cells, instead of a single broad spot. Each cell is associated with a spot to which a frequency band is attributed. In the case of the loss of a spot associated with a cell, designated a faulty cell, the spot (FR1, FR2, FB1, FB2, FV1, FV2) associated with at least one contiguous cell (CR1, CR2, CB1, CB2, CV1, CV2) to the said faulty cell is likewise associated with a part of the said faulty cell so that the area (CPJ′) of said faulty cell is reduced.

摘要： The present invention relates to a method of error correction coding for a channel with quasi-periodic fade, such as the RSC (railroad satellite channel). According to an embodiment, it uses a block code (N, K) in which the parity check matrix comprises a sub-matrix obtained by horizontal concatenation of a plurality of identity matrices. The coding applies preferably to the level of the link layer, on data packets of the physical layer, without prior interleaving of said packets.

摘要： A device for generating Orbital Angular Momentum (OAM) modes for radio communications. The device is designed to receive one or more input digital signals, each of which has a respective sampling period which is a respective multiple of a given sampling period, and occupies a frequency bandwidth which is a respective fraction of a given available frequency bandwidth. The device is operable to apply, to each input digital signal, a respective space modulation associated with a respective OAM mode having a respective topological charge to generate a corresponding digital signal carrying the respective OAM mode. The device is configured to apply, to each input digital signal, the respective space modulation by interpolating said input digital signal and phase-modulating the interpolated input digital signal so as to generate a corresponding phase-modulated digital signal carrying the respective OAM mode, having the given sampling period, and occupying the given available frequency bandwidth.
