Patent number: 9712211Abstract: A quadrature demodulator not requiring analog mixers. The demodulation is made using a first integrator and a second integrator which are controlled by square logic signals at twice the frequency of the carrier, the received signal being alternatively integrated by the first integrator and the second integrator over periods of time equal to a quarter period of time of the carrier frequency. The samples of the first and second integrators are sampled and subtracted from each other. The successive samples are combined in a first and a second combining module for providing in-phase and quadrature component samples. This demodulator can further be provided with a synchronization module IQ and a symbol synchronization module.Type: GrantFiled: July 7, 2016Date of Patent: July 18, 2017Assignee: COMMISSARIAT A L'ENERGIES ALTERNATIVESInventors: Pierre Courouve, Jean-Baptiste Dore, Manuel Pezzin

Patent number: 9692626Abstract: A RFID VHBR receiver including a quadrature digital demodulator, a symbol synchronization module at the baud rate and a PSK demodulator. The symbol synchronization module receives the in-phase and quadrature samples from the demodulator and extracts the components of the PSK symbols at the baud rate by selecting a decimation point in time. This synchronization is made by taking advantage of the particular structure of the preamble of the transmission frame in a RFID VHBR receiver.Type: GrantFiled: July 7, 2016Date of Patent: June 27, 2017Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Pierre Courouve, Jean-Baptiste Dore, Manuel Pezzin

Publication number: 20170012808Abstract: The invention relates to a RFID VHBR receiver comprising a quadrature digital demodulator, a symbol synchronization module at the baud rate and a PSK demodulator. The symbol synchronization module (200) receives the in-phase and quadrature samples from the demodulator and extracts the components of the PSK symbols at the baud rate by selecting a decimation point in time. This synchronization is made by taking advantage of the particular structure of the preamble of the transmission frame in a RFID VHBR receiver.Type: ApplicationFiled: July 7, 2016Publication date: January 12, 2017Applicant: Commissariat A L'Energie Atomiqe et aux Energies AlternativesInventors: Pierre COUROUVE, Jean-Baptiste DORE, Manuel PEZZIN

Patent number: 9438307Abstract: A robust time shift tracking UWB receiver. After translating in baseband by a quadrature demodulator, the received UWB pulsed signal is integrated on successive time windows, and then sampled. The complex samples are then correlated with a coding sequence from the transmitter and then transmitted on the one hand to a phase estimator and a demodulating/detecting module. The latter estimates the symbol emitted and provides it to the estimator which removes the modulation effect for estimating, at each time-symbol, the phase of the complex samples. A phase rotation follow-up module determines a compensated phase rotation and a non-compensated phase rotation from a reference instant. Controlling means deduce from the non-compensated phase rotation a time offset to be applied to the integration windows.Type: GrantFiled: June 15, 2015Date of Patent: September 6, 2016Assignee: Commissariat a l'energie atomique et aux energies alternativesInventors: Francois Dehmas, Laurent Ouvry, Manuel Pezzin

Patent number: 9083447Abstract: A receiver of electromagnetic and a method for receiving electromagnetic signals transmitted in a frequency band having a predetermined upper limit fMAX and representing a stream of information by means of a modulation of pulses at a predetermined average pulse repetition frequency fPRP. The receiver includes an input stage including a band-pass filter and applys processing without changing frequency of the signals and a sampler of the processed signals operating at a sampling frequency fe that is an integer multiple of the average pulse repetition frequency fPRP and less than said upper limit fMAX.Type: GrantFiled: November 21, 2006Date of Patent: July 14, 2015Assignee: COMMISSARIAT A.

Publication number: 20050041725Abstract: This invention relates to a receiver of an ultra wide band signal and the associated method. The receiver comprises: means (7) of outputting two orthogonal signals by projection of the received signal (R(t)) onto two periodic orthogonal functions with frequency approximately equal to the central frequency of the received signal, sampling means (7) of two orthogonal signals to output a discrete data stream (X(k), Y(k)) with two components, estimating means (8) for calculating a reference signal starting from the discrete data stream with two dimensions, and comparison means (9) for comparing all or some of the data contained in the discrete data stream with all or part of the data forming the reference signal. The invention is applicable to high-speed transmissions and positioning of transmitters/receivers.Type: ApplicationFiled: May 18, 2004Publication date: February 24, 2005Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUEInventors: Sebastien De Rivaz, Dominique Morche, Manuel Pezzin, Julien Keignart
