Optical frequency conversion by four-wave mixing (Bragg scattering) in a fiber is considered. The evolution of this process can be modeled using the signal and idler amplitudes, which are complex, or Stokes-like parameters, which are real. The Stokes-space formalism allows one to visualize power and phase information simultaneously, and produces ...
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 ...

Ethernet is positioning itself as an aggregation technology for carrier transport networks; however, as it was designed for local area networks, native bridged Ethernet does not fulfill all carrier requirements. Ethernet VLAN-label switching (ELS) has been designed to make Ethernet fulfill carrier requirements. ELS allows the creation of label switched ...

NON-STATIONARY MULTIPLE-ANTENNA INTERFERENCE CANCELLATION FOR UNSYNCHRONIZED OFDM SYSTEMS WITH DISTRIBUTED TRAININGSTAR, OPEN
- Kuzminskiy A.
Adaptive interference cancellation is addressed in an asynchronous orthogonal frequency-division multiplexing (OFDM) system with a frame containing a number of temporally distributed pilot symbols, e.g., as in the IEEE 802.16-2004 standard. Non-stationary symbol-by-symbol switching technique is proposed that is based on banks of the second-order statistics semi-blind solutions with on-line ...
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 FabryPérot resonator embedding a near infrared ...
