Analyse

Afin d’évaluer la possibilité d’utiliser la diversité de fréquence pour combattre les effets de la propagation par trajets multiples. nous avons étudié les corrélations entre les affaiblissements mesurés sur 16 raies de fréquences fixes réparties dans une bande de 1 GHz de large. La grande différence de comportement des diverses raies permet d’envisager la mise en æuvre de systèmes travaillant en diversité de fréquence.

Abstract

In order to evaluate the possibility of using frequency diversity to counteract selective effects due to multipath propagation, the signal amplitude behavior has been investigated on a 1 GHz — wide frequency band. The analysis shows a great variability accross the band-width and suggests a possible improvement of the availability of a line of sight link by implementing frequency diversity devices.
