  • Spreading technique applied to broadband mobile communications by satelite relying on DVB-RCS
    Patent number: 8711955
    Abstract: A device (D1) is dedicated to the processing of signals to be transmitted by waves, within a communication terminal (T). This device (D 1) includes i) memory (M1) for temporarily storing a sequence of digital samples of an analogue input signal according to a first sampling frequency and in a manner synchronized with respect to starts of periodic time slots, and ii) digital/analogue conversion (CV2) for generating, during each time slot and according to a second sampling frequency equal to N times the first sampling frequency, with N an integer strictly greater than 1, an analogue output signal, to be transmitted, representative of N repetitions of the sequence of digital samples that is stored in the memory (M1) during the time slot concerned, so as to output the analogue signal according to a symbol rate equal to N times a reference symbol rate.

  • SPREADING DEVICE AND DESPREADING DEVICE FOR RADIO COMMUNICATIONS IN THE PRESENCE OF AN OFF-AXIS POWER SPECTRAL DENSITY CONSTRAINT
    Publication number: 20110064116
    Abstract: A device (D1) is dedicated to the processing of signals to be transmitted by waves, within a communication terminal (T). This device (D1) comprises i) memory means (M1) for temporarily storing a sequence of digital samples of an analogue input signal according to a first sampling frequency and in a manner synchronized with respect to starts of periodic time slots, and ii) digital/analogue conversion means (CV2) for generating, during each time slot and according to a second sampling frequency equal to N times the first sampling frequency, with N an integer strictly greater than 1, an analogue output signal, to be transmitted, representative of N repetitions of the sequence of digital samples that is stored in the memory means (M1) during the time slot concerned, so as to output the analogue signal according to a symbol rate equal to N times a reference symbol rate.

  • Device and Method for Processing Data by Modulating Sets of Spreading Pseudocodes as a Function of Data Destination Cells for a Multi-Beam Communication Satellite
    Publication number: 20080298439
    Abstract: A device (D) is dedicated to the processing of data by spread spectrum coding for a multi-beam communication satellite (S), each beam (B1-B6) of which is associated with a terrestrial cell (C1-C6) contained in a satellite coverage zone (ZC).
