Afin de développer les futurs systèmes de communication Ultra Large Bande (ULB), une modélisation réaliste du canal de propagation est nécessaire. Cet article présente une étude expérimentale du canal radio ULB, basée sur une campagne de sondage complète réalisée en environnement intérieur de bureau. Nous présentons les caractéristiques principales du canal ULB en termes de pertes par propagation, puis de paramètres large bande, comme la dispersion des retards et la pente du profil puissance-retard. À partir de ces analyses, nous proposons un modèle de canal statistique qui permet de reproduire les effets du canal ULB sur la bande de fréquences 3,1–10,6 GHz.
For the development of future Ultra Wide Band (UWB) communication systems, realistic modeling of the propagation channel is necessary. This article presents an experimental study of the UWB radio channel, based on an extensive sounding campaign covering the indoor office environment. We consider the main characteristics of the UWB channel by studying the propagation loss and wide band parameters, such as the delay spread and the power delay profile decay. From this analysis, we propose a statistical channel model reproducing the UWB channel effects over the frequency bandwidth 3.1–10.6 GHz.
