Patent number: 10382116Abstract: The invention relates to a radio communication receiver receiving a radio signal (S) including a main polarisation (MAIN-POL) and a secondary polarisation (X-POL) orthogonal to the main polarisation (MAIN-POL), the receiver including: a unit (1) for receiving the main polarisation (MAIN-POL) and the secondary polarisation of the received signal, synchronised as a carrier frequency with the main polarisation (MAIN-POL); a unit (2) for cancelling out the secondary polarisation synchronised with the main polarisation (MAIN-POL) and configured to suppress, from the received signal (S), the interference due to the secondary polarisation (X-POL), the unit (2) for cancelling out the secondary polarisation including a filtering unit (21) that receives the main polarisation (MAIN-POL) and the secondary polarisation (X-POL) as input; a unit (3) for demodulating the filtered signal, located downstream of the cancellation unit and configured to calculate carrier frequency error information and to communicate same by feedType: GrantFiled: January 27, 2017Date of Patent: August 13, 2019Assignees: Zodiac Data Systems, CENTRE NATIONAL D'ETUDES SPATIALESInventors: Nicolas Pasternak, Alain Thomas, Clément Dudal, Mathieu Llauro, Jean-Pierre Millerioux

Patent number: 9484956Abstract: The invention relates to a method for correcting a message the generation of which involves transforming an initial message and inserting bit stuffing into the transformed message, which method comprises providing an observation sequence containing the message to be corrected. A number of path hypotheses are generated via a trellis diagram associated with the transformation. The nodes of the trellis diagram each represent a state of a finite-state machine capable of transforming the initial message and the branches represent the possible transitions between nodes. Among the branches of the trellis diagram, certain represent conditional transitions that may be made only when bit stuffing is present. During the generation of a path hypothesis, bit stuffing is detected and the branches taken are those associated with the detected bit stuffing. The most likely path hypothesis relative to the observation sequence is finally retained.Type: GrantFiled: January 3, 2012Date of Patent: November 1, 2016Assignee: CENTRE NATIONAL D'ETUDES SPATIALES ( C.N.E.S.)Inventors: Raoul Prevost, David Bonacci, Martial Coulon, Jean-Yves Tourneret, Julia Le Maitre, Jean-Pierre Millerioux

Patent number: 9184769Abstract: The method according to the invention relates to the decoding of a sequence of symbols, the sequence of symbols having been generated by: calculating a CRC value for an initial message; combining the initial message and the CRC value so as to produce a transformed message; and, encoding the transformed message. The decoding comprises: generating a number of path hypotheses via a trellis diagram corresponding to the trellis diagram of a finite-state machine comprising the encoder and the CRC generator, in which the encoder and the CRC generator are supplied with the same input. According to a preferred embodiment of the method, the trellis diagram is adapted to take into account bit stuffing possibly inserted in the transformed message before encoding.Type: GrantFiled: January 3, 2012Date of Patent: November 10, 2015Assignee: CENTRE NATIONAL D'ETUDES SPATIALES (C.N.E.S.)Inventors: Raoul Prevost, David Bonacci, Martial Coulon, Jean-Yves Tourneret, Julia Le Maitre, Jean-Pierre Millerioux

Patent number: 8976895Abstract: Method for calibrating a linearizer and linearized electronic component the method comprises predistortion, in a predistortion linearizer, of a signal upstream of an electronic component to compensate nonlinear distortion. Determining predistortion setting parameters comprises applying a bifrequency test signal to the component and measuring the relative amplitudes of the lines at the output of the component. A variable indicative of the magnitude |Kp| of the AM/PM conversion coefficient of the component is calculated on the basis of these measurements. The predistortion setting parameters are adjusted so as to minimize |Kp|. The method may in particular be implemented in a linearized amplifier device and in an amplifier test bench.Type: GrantFiled: May 29, 2013Date of Patent: March 10, 2015Assignee: Centre National d'Etudes SpatialesInventors: Jacques Sombrin, Xavier Giraud, Alexandre Guerin, Guy Lesthievent, Jean-Pierre Millerioux, Xavier Deplancq
