Abstract
Radio channel observation and characterization is indispensable in mobile communications systems development. Efficient propagation prediction is crucial for rapid and cost-effective systems deployment. On-site measurements, statistical models, propagation prediction and deterministic modeling are widely used for the qualification of radio channels. In this paper, a simulation tool for deterministic channel modeling in indoor environments is evolved. A hybrid combination of the Method-Of-Moments (MoM) and the Uniform Theory of Diffraction (Utd) is used. Statistical characteristics of a simple office room are calculated and the results are in excellent agreement with corresponding results of relative research on the field.
Résumé
L’observation et la caractérisation du canal de propagation sont indispensables au développement des systèmes de radiocommunication avec les mobiles. Une bonne estimation de la propagation est critique pour le déploiement rapide et à faible coût des systèmes. Des mesures in situ, des modèles statistiques et déterministes de propagation radioélectrique sont largement utilisés pour la qualification du canal de propagation. Dans l’article présenté, un outil d’ingénierie radioélectrique de modélisation déterministe du canal de propagation a été développé. Il est basé sur une méthode hydride combinant la Méthode des Moments et la Théorie Uniforme de la Diffraction. Les caractéristiques statistiques en environnement bureau sont évaluées et les résultats sont conformes aux résultats des recherches correspondantes.
