[Modèles des canaux de propagation des systèmes de communication mobile]
Les caractéristiques du canal de propagation impactent le développement des systèmes de communication radio mobile. Lors de la conception, la connaissance des caractéristiques du canal permet de déterminer l'interface radio la mieux adaptée (modulations, codage, type d'accès…). Les modèles de canaux large bande permettent alors d'évaluer et de comparer différentes interfaces radio candidates. En phase de déploiement réel, les modèles de prévision fournissent de précieuses données pour l'optimisation de l'architecture et du paramétrage du réseau radio. Cet article a pour but de rappeler brièvement les principales techniques de caractérisation et les méthodes utilisées pour modéliser le canal de propagation.
Propagation channel properties influence the development of wireless communication systems. During system design, channel properties are required to choose the suitable air interface (modulation, coding and access scheme). Comparisons and assessment of different solutions are performed using wideband propagation channel models. During network planning, prediction channel models provide valuable inputs to optimize network parameters. This article aims to present a short overview of these different propagation channel models.
