Publication number: 20230208438Abstract: The present invention relates to a method of compressed sensing of a spectrally-sparse signal within a given spectral band, the received signal being mixed (820) over a sensing frame with a pulse train scrolling with a repetition frequency linearly modulated over time within this frame. The result of mixing is filtered (830) by means of a low-pass filtering and sampled (840) at a non-uniform rate equal to the repetition frequency, to result in complex samples representative of the received signal. The spectrum of the received signal can be estimated by weighting by means of the complex samples the spectral values of a pulse into a plurality of frequency equidistributed in the band, and by summing up these weighted values for each of these frequencies. An estimate of the received signal is thereby deduced by inverse Fourier transform. The spectral band can be scanned based on the spectrum thus estimated.Type: ApplicationFiled: December 28, 2022Publication date: June 29, 2023Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Mykhailo ZARUDNIEV, Michael PELISSIER, Jorge-Luis GULFO MONSALVE

Patent number: 10868701Abstract: The present invention relates to a wavelet bandpass sampling method, with low aliasing and a corresponding device. The analogue signal to sample is correlated with a sequence of wavelets succeeding each other with a rate fp of which the positions in the sequence are temporally modulated from arguments of a CAZAC sequence, notably a Zadoff-Chu sequence. The correlation results are next sampled at a frequency fs?fp and digitally converted to provide a compressed representation of the signal. The temporal modulation of the positions of the wavelets makes it possible to obtain incoherent aliasing of the correlation signal in the sampling band and thereby to reduce aliasing.Type: GrantFiled: November 29, 2019Date of Patent: December 15, 2020Assignee: Commissariat A L'Energie Atomique et aux Energies AlternativesInventors: Michael Pelissier, Marguerite Marnat

Patent number: 8290029Abstract: A super-regenerative transceiver that has an antenna interface for an antenna is self-tuned with a self-tuning unit configured. The self-tuning unit makes the transceiver to repeatedly perform a self-tuning cycle until the amplitude meets a predetermined detection condition or a predetermined criterion is met. The self-tuning cycle involves the following: transmitting to the antenna a probe signal with one or more pulses; receiving from the antenna a ringing detection signal; determining if the ringing detection signal reflects tails of the probe signal with amplitude meeting a predetermined detection condition; and adjusting of the tuning of the super-regenerative transceiver if the amplitude does not meet the predetermined detection condition.Type: GrantFiled: March 25, 2011Date of Patent: October 16, 2012Assignee: Nokia CorporationInventors: Joni Jorma Marius Jantunen, Jaakko Valtteri Varteva, Jari-Jukka Harald Kaaja, Risto Heikki Sakari Kaunisto, Bertrand Gomez, Michael Pelissier
