Ambiguity function and Cramer-Rao bounds for standard and new modified Costas signals

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Yassin El Hillali, Atika Rivenq

The Cramer-Rao bound (CRB) gives a lower variance bound that an estimator can achieve. Presented is a mathematical approach to estimate it for specific radar signals, namely Costas signals and their modified versions. The modified versions design consists in widening Costas frequency hops and...

QAM-32/0.588 THz communication using electronic Schottky transceivers

Guillaume Ducournau, Pascal Szriftgiser, Denis Bacquet, Emilien Peytavit, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

We report on THz communication system using vectorial modulations schemes above 500 GHz. Using schottky-based electronic technologies at 588 GHz, potentialities of high-level multi-carrier modulation schemes for wireless links are analyzed. The wireless link is composed of an emitter with sub-...

Semi-digital FIR DAC for low power single carrier IEEE 802.11ad 60GHz transmitter

Fikre Tsigabu Gebreyohannes, Antoine Frappé, Andreas Kaiser

IEEE 802.11ad (WiGig) is an emerging multi-Gb/s wireless standard in the unlicensed 60GHz spectrum. This work presents system level validation of a Single Carrier (SC), QPSK modulated WiGig transmitter based on a semi-digital Finite Impulse Response (FIR) Digital-to-Analog Converter (DAC). The 1....

Theoretical and experimental analyses of tunable Fabry-Perot resonators using piezoelectric phononic crystals

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes are conducted. The presented structures exhibit Bragg band gaps that can be switched on or off by setting electrodes in short or open circuit. The band gap frequency...

Characterization of flexible CMOS technology tranferred onto a metallic foil

Justine Philippe, Aurelien Lecavelier Des Etangs-Levallois, Philip Latzel, Francois Danneville, J.F. Robillard, Daniel Gloria, Emmanuel Dubois

In this work we demonstrate a method to transfer high-performance industrial CMOS circuits thinned down to 5.7 mu m and bond onto a 25-mu m-thick stainless steel foil with a 800-nm-thick indium layer. The bonding is performed at the temperature of 100 degrees C with an applied pressure of 1.2 bar....

Estimation of the area of a reverberant plate using average reverberation properties

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad

This paper aims to present an original method for the estimation of the area of thin plates of arbitrary geometrical shapes. This method relies on the acquisition and ensemble processing of reverberated elastic signals on few sensors. The acoustical Green's function in a reverberant solid...

Tonpilz Underwater Acoustic Transducer Integrating Lead-free Piezoelectric Material

Rémi Rouffaud, Christian Granger, Anne-Christine Hladky, Mai Pham Thi, Franck Levassort

A Tonpilz transducer based on lead-free piezoelectric material was fabricated, modeled and characterized. The stack is composed of two rings of doped BaTiO 3. This composition was initially chosen due to good electromechanical performance (k t at 40%) and high mechanical quality factor (Q m over...

Two-frequency excitation of single-mode Faraday waves

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

The purpose of this work is to investigate, for the first time, excitation of Faraday waves in small containers using two commensurate frequencies. This spatial restriction, which is encountered at low frequencies, leads to a wave composed primarily of one spatial eigenmode of the container. When...
