Impulsive noise on indoor power lines: characterization and mitigation of its effect on PLC systems

Virginie Degardin, M. Lienard, Pierre Degauque, A. Zeddam, F. Gauthier

Intensive measurements of impulsive noise have been carried out on indoor power lines. From this approach, various types of transients are classified and a stochastic noise model is deduced from the statistical analysis of their main characteristics. A power line communication, based on an OFDM…

AlGaN/GaN HEMTS: material, processing, and characterization

F. Calle, T. Palacios, E. Monroy, J. Grajal, M. Verdu, Zahia Bougrioua, Ingrid Moerman

The growth of AlGaN/GaN high electron mobility transistor (HEMT) structures on sapphire by metal organic vapor phase epitaxy (MOVPE) is described, with special emphasis on procedures to reduce dislocation density. All the processing steps involved in the fabrication of nitride-based HEMTs have been…

Directional photon transfer between two wires

L. Dobrzynski, Abdellatif Akjouj, Bahram Djafari-Rouhani, Jerome O. Vasseur, Mohamed Bouazaoui, Jean-Pierre Vilcot, Arnaud Beaurain, Stefan Mc Murtry

The directional transfer of a single photon from one wire to another, leaving all other neighbor states unaffected, is of great importance. We present a simple coupling structure that makes such transfer possible, for any given photon wavelength and linewidth. We give closed-form expressions for…

Optoelectronic components and integrated circuits including up and down conversion techniques and hybrid integration technology

Didier Decoster, Samuel Dupont, V. Magnin

Microwave optical links can be considered as basic bricks for some emerging system applications such as optically supplied microwave antennas. Emitters, optical switching matrices, high speed photodetectors and specific components for up or down conversion, are generic devices or functions for…

Evidence of an impurity band at an n-GaN/sapphire interface

C. Mavroidis, J.J. Harris, R.B. Jackman, Z. Bougrioua, I. Moerman

We report on temperature-dependent differential Hall-effect and resistivity measurements, between 10 and 300 K, on a silicon-doped GaN epitaxial layer grown by metalorganic chemical vapor deposition on a sapphire substrate. Reactive ion etching has been used to enable Hall measurements to be taken…

Statistical Estimation of Fast Varying Channels for Cellular Mobile Telecommunications Systems

Iyad Dayoub, M. Zaizouni, Atika Rivenq, Jean-Michel Rouvaen

The time variant environment in fast channels severely impacts on the performances of classical equal-ization techniques. A method is proposed here to circumvent this problem, particularly in the severe channel with fast behaviour. To improve the Bit Error Rate (BER) at the receiver, a new approach…
