Estimation of 60-GHz channels based on energy detection

Stephane Mebaley-Ekome, Laurent Clavier, Antoine Frappé, Eric Pierre Simon, Ilias Sourikopoulos

Estimation of time-varying channels is a common challenge for receiver architectures in wireless communications. Coherent receivers may require good knowledge of the channel impulse response for demodulation of the received symbols, after equalization of a dense multipath channel. However, very few...

Highly tunable Fabry-Perot resonators using piezoelectric phononic crystals

Bertrand Dubus, Marie -Fraise Ponge, Anne-Christine Hladky, Jerome O. Vasseur, Mai Phamthi

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes, are conducted. These structures are shown to exhibit Bragg band gaps which are switched on or off by setting electrodes in short or open circuit. Band gap frequency...

A modal formulation for the propagation of guided waves in straight and curved pipes and the scattering at their junction

M. El Bakkali, A. Lhémery, V. Baronian, Sébastien Grondel

The well-established semi-analytic finite element (SAFE) method for predicting guided wave propagation in straight guides is extended to deal with curved pipes using curvilinear coordinates system, following developments by Treyssède and Laguerre [J. Sound Vib. 329 1702-16 (2010)] for helical wires...

A synthesis of theoretical and experimental study on power line communication over an aircraft tree-shaped network

Virginie Degardin, Pierre Laly, M. Lienard, Pierre Degauque

This paper gives an overview of the theoretical and experimental approach which has been carried out in order to study the feasibility of broadband power line communication in aircraft. The network which has been chosen corresponds to part of a cabin lighting system and whose tree shape...

Sensing light and sound velocities of liquids in two-dimensional phoxonic crystals

Samira Amoudache, Rayisa Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, Antoine Khater, Ralf Lucklum, Rachid Tigrine

We study theoretically the potentiality of dual phononic-photonic (the so-called phoxonic) crystals for liquid sensing applications. We investigate the existence of well-defined features (peaks or dips) in the transmission spectra of acoustic and optical waves and estimate their sensitivity to the...

Ultralow-phase-noise oscillators based on BAW resonators

Mingdong Li, Seonho Seok, Nathalie Rolland, Paul-Alain Rolland, Hassan El Aabbaoui, Emeric de Foucauld, Pierre Vincent, Vincent Giordano

This paper presents two 2.1-GHz low-phase noise oscillators based on BAW resonators. Both a single-ended common base structure and a differential Colpitts structure have been implemented in a 0.25-μm BiCMOS process. The detailed design methods including the realization, optimization, and test are...
