Abstract
This paper investigates the performance of a compact space-time diversity receiver for mobile communication systems. Expressions for the bit error rate and outage meanSnr are derived as a function of the channel covariance matrix. These results define the sensitivity of the performance of such a receiver to the environment (fading characteristics and angular spread) and the antenna array (geometry and coupling). Furthermore, these results are validated for a practical antenna system.
Résumé
Dans cet article, les performances d’un récepteur compact fournissant une diversité d’espace et de trajet dans le contexte d’un systeme de communications mobiles sont étudiées. Les expressions de la probabilité d’erreur sur les bits et d’un rapport signal sur bruit moyen minimal sont déterminées en fonction de la matrice de covariance du canal. Ces résultats permettent d’évaluer la sensibilité des performances à l’environnement (caractéristiques des évanouissements, dispersion angulaire) et à l’antenne en réseau (géométrie et couplage). A titre d’illustration, des résultats expérimentaux montrent les performances d’une antenne en réseau particulière.
