Intra-vehicle digital communications: characterization and simulation of the electromagnetic environment
[Communication intra véhicule : caractérisation et simulation de l'environnement électromagnétique]
Comptes Rendus. Physique, Volume 10 (2009) no. 1, pp. 22-30.

La plupart des travaux sur les bruits et les sources potentielles d'interférences ont été menés en vue de la protection des communications analogiques et s'avèrent actuellement insuffisants, compte tenu de la généralisation des communications numériques. De nouvelles approches sont en cours de développement et nous avons choisi d'illustrer les démarches actuelles en s'appuyant sur une application particulière qui concerne les transmissions au sein d'un véhicule. Le cas d'une transmission filaire sur le réseau d'énergie, connue sous le nom de courants porteurs en ligne, et celui de liaisons de type sans fil, seront successivement envisagés. Nous nous intéresserons à la caractérisation de l'environnement, du point de vue brouillage électromagnétique, mais nous mettrons également en évidence les potentialités des chambres réverbérantes pour simuler, de façon reproductible, un environnement multi trajets.

Most of the studies on electromagnetic noise and the potential sources of interference were conducted to protect analog communications and have now appeared to be insufficient given the widespread development of digital communications. New approaches appropriate for digital communications are currently under development. We have chosen to illustrate these recent approaches by focusing on the particular application of intra-vehicle transmission. In this article, we consider two examples of data transmission: wire transmissions over a power line network, better known as power line communication, and wireless links inside the vehicle's passenger cell. We focus on characterizing the electromagnetic environment but we also highlight the potential of reverberation chambers for reproducibly simulating multi-path environments.
