This paper addresses the impact of telephone transmission channels on automatic speech recognition (ASR) performance. A real-time simulation model is described and implemented, which allows impairments that are encountered in traditional as well as modern ...

The goal of TAXYS is to provide a framework for developing real-time embedded code and verifying its correct behavior with respect to quantitative timing requirements. To achieve so, TAXYS connects France Telecom's ESTEREL compiler SAXO-RT with VERIMAG's m ...
The transmission of energy or signals to a rotating device is generally carried out by systems with sliding contacts. This technology, apparently simple, generates serious nuisance such as abrasion of the elements in contact, electric noises and requires a ...
Many communication systems are {\em bandwidth-expanding}: the transmitted signal occupies a bandwidth larger than the {\em symbol rate}. The sampling theorems of Kotelnikov, Shannon, Nyquist et al. shows that in order to represent a bandlimited signal, it ...
We consider the problem of sampling signals which are not bandlimited, but still have a finite number of degrees of freedom per unit of time, such as, for example, piecewise polynomials. We demonstrate that by using an adequate sampling kernel and a sampli ...
This paper introduces telecommunication services engineering through a definition of services, of network architectures that run services, and of methods, techniques and tools used to develop services. We emphasize the Intelligent Network (IN), the Telecom ...
This document presents a new research domain in the area of communication systems. It is meant to be the proposal of the Communication Systems Division of EPFL and its Consortium to the National Pole of Competence of the Swiss National Fund. The expected ( ...

The ever-growing popularity of the Internet is dramatically changing the landscape of the communications market place. The two separate worlds of the Internet and Telecommunications are converging. The respective advantages of the two environments are bein ...
