CAPACITY DEMAND AND TECHNOLOGY CHALLENGES FOR LIGHTWAVE SYSTEMS IN THE NEXT TWO DECADES

  • Desurvire E.

Ten to 20 years from now, optical networks will have to carry vastly increased amounts of Internet traffic. Today's knowledge (2006) already points to ultimate technology limits in the physical layer, foretelling the end of the so-called "Optical Moore's Law." Such an observation is discordant with the generic and optimistic ...

COMPETITIVE SCHEDULING FOR OFDMA SYSTEMS WITH GUARANTEED TRANSMISSION RATE

  • Jiao W

Next-generation broadband wireless standards use orthogonal frequency division multiple access (OFDMA) as the preferred physical layer multiple access scheme, especially for the downlink. Due to limited resources available at the base station, multi-user resource allocation is crucial for delivering the applications with various quality-of-service (QoS) demands. We study the OFDMA ...

GAN ON SI WITH NM-THICK SINGLE-CRYSTAL SC2O3 AS A TEMPLATE USING MOLECULAR BEAM EPITAXY

  • Ng H.

The epitaxial growth of GaN on Si (1 1 1) substrates has been performed using plasma-assisted molecular beam epitaxy with a thin (19.3 nm) single-crystal layer of Sc2O3 as a template/buffer layer. The structural properties and in situ epitaxial growth were studied using reflection high energy electron diffraction (RHEED), high-resolution ...

THE TAX IDENTITY IN RISK THEORY — A SIMPLE PROOF AND AN EXTENSION

  • Borst S.

By linking queueing concepts with risk theory, we give a simple and insightful proof of the tax identity in the Cramér–Lundberg model that was recently derived in Albrecher & Hipp [Albrecher, H., Hipp, C., 2007. Lundberg’s risk process with tax. Blätter der DGVFM 28 (1), 13–28], and extend the identity ...

PINNING MODE RESONANCES OF TWO-DIMENSIONAL ELECTRON STRIPE PHASES AT HIGH LANDAU LEVELS

  • Pfeiffer L.
  • Tsui D.
  • West K.

This paper presents the radio-frequency (rf) diagonal conductivity spectra of two-dimensional electrons in the second excited and higher Landau levels, and in particular shows isotropic pinning mode resonances in the bubble phases evolving into a highly anisotropic rf resonance in the stripe phase. The stripe phase resonance is observed for ...

SIGNAL PROCESSING ENHANCING OBJECTIVE EVALUATION OF SPEECH QUALITY ALGORITHM: CURRENT EFFORTS, LIMITATIONS AND FUTURE DIRECTIONS

  • Lee M.
  • Lee W.
  • Mcgowan J

We discuss a performance improvement over the current state-of-the-art objective speech quality assessment algorithm by means of a parameter study. The state-of-the-art algorithm computes a certain measure of disturbances surface, and applies a cognitive model to map the computed value to the scale used mean opinion score (MOS). We note ...

MECHANICAL DESIGN AND FABRICATION OF MULTI-LAYER INDIUM PHOSPHIDE FREESTANDING MICROSTRUCTURES FOR A MOEMS MICROSPECTROMETER

  • Garrigues M.
  • Parillaud O.

The aim of this paper is to report on the optimization of major technological steps in the fabrication of a micro-opto-electro-mechanical system (MOEMS) composed of an actuable stack of free-standing indium phosphide layers. The projected MOEMS device is a microspectrometer based on a tunable Fabry–Pérot resonator embedding a near infrared ...
