Abstract

L'invention porte sur un système de communication capable de traiter des signaux RF de différentes normes à l'aide d'une même antenne. Ledit système comporte une unité émettrice présentant: au moins une sortie (26) d'émission de signaux RF d'information, au moins une entrée (24) de réception de signaux RF d'information, et une entrée de réception de signaux RF d'information GPS. L'unité émettrice comporte: un modulateur (16) modulant la FI d'émission à l'aide du signal d'information en bande de base émis pour produire le signal d'information FI émis; et un élévateur de fréquence convertissant le signal d'information FI à l'aide du signal RF émis pour produire au moins un signal RF d'information émis.
