Il est actuellement nécessaire de développer une nouvelle bande de fréquences pour permettre la création de systèmes de communication mobile de nouvelle génération. Parmi les bandes potentielles, la bande des 3 GHz et des hyperfréquences est la plus prometteuse. Des études expérimentales sur les caractéristiques de retard de la propagation par trajets multiples doivent être menées afin d'obtenir une transmission à grande vitesse dans la bande des micro-ondes. Nous avons développé un système de mesure du profil de retard de propagation du haut débit micro-ondes sur des bandes passantes étalées de 100 MHz dans les bandes de 3, 8 et 15 GHz. Nos expériences ont confirmé les performances du système avec une résolution de 20 ns, un retard mesurable maximum de 40 µs, une erreur d'amplitude relative inférieure à 3 dB et une plage dynamique supérieure à 60 dB. Nous avons utilisé notre système pour mesurer des profils de retard sur une zone urbaine avec visibilité directe, notamment en termes d'effets de hauteur d'antenne mobile. Des exemples typiques sont présentés. L'analyse a montré que les écarts de retard augmentaient avec la distance d'émission/réception et diminuaient avec la hauteur de l'antenne.

Abstract: There is currently a need for development of a new frequency band to enable creation of next-generation mobile communication systems. Of the potential bands, the 3 GHz and over microwave band holds the greatest promise. Experimental studies on the delay characteristics of multipath propagation must be conducted in order to achieve high-speed transmission in the microwave band. We have developed a system for measuring the microwave broadband propagation delay profile over 100 MHz spread bandwidths in the 3, 8 and 15 GHz bands. Our experiments confirmed system performances of 20-ns resolution, 40-µs maximum measurable delay, relative amplitude error of within 3 dB and dynamic range of over 60 dB. We used our system to measure delay profiles on an urban area with line of sight, particularly, in terms of the effects of mobile antenna height. Typical examples are presented. Analysis showed that delay spreads increased with transmit/receive distance and decreased with the higher antenna height.
