Assisted Channel Estimation with Dynamic Allocation Pilot Subcarriers for OFDM Communications

Boudali Ouarzazi, Atika Rivenq, Iyad Dayoub, Marion Berbineau

In this paper, a transmission system based on OFDM (Orthogonal Frequency Division Multiplexing) technique and channel estimation is proposed. The idea is to enhance the assisted channel estimation without data rate loss. A solution based on frequency diversity is proposed. With the same number of...

Rotational temperatures in RF plasma of Ar-H2O mixtures at low and moderated pressure

Adriana Annusova, Jaroslav Krištof, Corinne Foissac, Pavel Veis, Philippe Supiot

An Ar-H2O discharge with Ar content from 0 to 95 % at 67 and 266 Pa have been studied by optical emission spectroscopy. The plasma was excited at 27 MHz by a helical cavity with a power set at 30 W. The rotational temperatures of N2(C3Πu) and OH(A2 Σ + ) emitters were determined through spectral...

Toward the understanding of the interfacial dairy fouling deposition and growth mechanisms at a stainless steel surface : a multiscale approach

M. Jimenez, Guillaume Delaplace, N. Nuns, S. Bellayer, D. Deresmes, G. Ronse, G. Alogaili, M. Collinet-Fressancourt, M. Traisnel

The microstructures of two dairy fouling deposits obtained at a stainless steel surface after different processing times in a pilot plate heat exchanger were investigated at different scales. Electron-Probe Micro Analysis, Time-of-Flight Secondary Ion Mass Spectrometry, Atomic Force Microscopy, and...

Open problems in mathematical modelling and physical experiments: exploring exponential function

Raffaele Pisano, Paolo Bussotti

Generally speaking the exponential function has large applications and it is used by many non physicians and non mathematicians, too. Nevertheless some crucial and practical problems happen for its mathematical understanding. Mostly, this part of mathematical cognitive programmes introduce it from...

Theory and Monte Carlo simulations for the stretching of flexible and semiflexible single polymer chains under external fields

F. Manca, S. Giordano, Pier Luca Palla, F. Cleri, L. Colombo

Recent developments of microscopic mechanical experiments allow the manipulation of individual polymer molecules in two main ways: uniform stretching by external forces and non-uniform stretching by external fields. Many results can be thereby obtained for specific kinds of polymers and specific...

Dynamics of confined cavity modes in a phononic crystal slab investigated by in situ time-resolved experiments

R. Marchal, Olga Boyko-Kazymyrenko, Bernard Bonello, Jinfeng Zhao, Laurent Belliard, Mourad Oudich, Yan Pennec, Bahram Djafari-Rouhani

The confinement of elastic waves within a single defect in a phononic crystal slab is investigated both experimentally and theoretically. The structure is formed by a honeycomb lattice of air holes in a silicon plate with one hole missing in its center. The frequencies and polarizations of the...

On the origin of basal stacking faults in nonpolar wurtzite films epitaxially grown on sapphire substrates

Philippe Vennéguès, Jean Michel Chauveau, Z. Bougrioua, Tiankai Zhu, Denis Martin, Nicolas Grandjean

The microstructure of nonpolar heteroepitaxial wurtzite films (GaN and ZnO-based) is dominated by the presence of planar basal stacking faults (BSFs). In this paper, transmission electron microscopy studies of both GaN and ZnO nonpolar films oriented either (11–20) or (1–100) and grown on sapphire...
