[Influence de la modélisation des environnements indoor sur les paramètres caractéristiques du canal MIMO]
La modélisation des environnements est un facteur déterminant pour la prédiction de la propagation des ondes radio réalisée par une méthode à tracé de rayons 3D. Ainsi, ce travail traite de l'influence de la finesse de description d'environnements indoor sur la caractérisation de canaux MIMO (Multiple Input Multiple Output) simulés. Deux scènes sont considérées : la première est un milieu de type hall ; la seconde est un espace plus confiné représentant un étage. Pour ces deux environnements, trois niveaux de description tant géométrique qu'électrique sont proposés. Les résultats produits sont obtenus par analyse de l'évolution de la capacité du canal et de la corrélation entre les différentes liaisons radio en fonction de la polarisation, du caractère LOS ou NLOS des liaisons, de l'espacement entre antennes et du nombre d'antennes à l'émission et à la réception.
Modelling of the environment is an important factor in electromagnetic wave propagation simulation, performed by a 3D ray-tracing method. The aim of this work is to study the effect of indoor environment modelling accuracy on MIMO (Multiple Input Multiple Output) channel characterisation. The first of the two environments investigated is the hall of our building, while the second one is a more confined environment and represents the floor of our laboratory. For these two indoor environments, three description levels are proposed in order to establish geometrical and electrical modelling impact on MIMO channel characterisation. Results are obtained by analysing the capacity and variation in correlation in relation to the polarisation, the presence of LOS (Line of sight) or NLOS configurations, the spacing between antennae and the number of transmitter and receiver antennae.
