Abstract

This paper deals with the performance of a compact dual diversity receiver. For this study we assume that the channel is characterized by a flat Rayleigh fading and that the incoming waves can be described by a Gaussian angular power distribution. The performance of a maximal-ratio-combiner in a correlated Rayleigh fading is given. These expressions are simplified and studied for the case of a dual diversity receiver. The influence of the mutual coupling between the sensors is taken into account using a simplified model. The results are compared with results obtained from realistic antenna simulations.

Résumé

Dans cet article, les performances d’un récepteur compact bicapteur realisant une diversité d’espace sont étudiées. Pour cette étude, on suppose que le canal est non selectif en frequénce et que les évanouissements suivent une loi de Rayleigh. De plus, la distribution des ondes incidentes sur le récepteur est supposée gaussienne. On rappelle les expressions analytiques des performances pour des canaux ne présentant pas l’hypothése classique d’indépendance. Ces expressions sont explicitées dans le cas d’un récepteur bicapteur. L’influence du couplage est mise en évidence en utilisant un modele simplifié. Une étude mettant en ozuvre une simulation d’antennes plus exacte permet de verifier les résultats obtenus et d’etudier plusieurs configurations.
