A first radio signal is received via a first satellite reception path, for example, an antenna or spot beam, which serves a satellite cell. The received first radio signal includes a desired satellite uplink signal transmitted from a first source using a frequency assigned to the satellite cell and an interfering signal transmitted from a second source using the frequency assigned to the satellite cell. A second radio signal is received via a second satellite reception path, for example, via another antenna or spot beam of the system and/or via a satellite antenna beam of another system. The second radio signal includes the interfering signal. The first and second radio signals are processed to recover the desired satellite uplink signal.

Selon l'invention, un premier signal est reçu par l'intermédiaire d'un passage de réception de satellite, par exemple, une antenne ou un faisceau étroit, ces derniers servant à une cellule satellite. Ledit premier signal radio comprend un signal de liaison montante satellite souhaité, transmis à partir d'une première source au moyen d'une fréquence attribuée à la cellule satellite et un signal d'interférence transmis à partir d'une seconde source au moyen de la fréquence attribuée à la cellule satellite. Un second signal radio est reçu par l'intermédiaire d'un second passage de réception satellite, par exemple, par l'intermédiaire d'une autre antenne ou d'un faisceau étroit du système et/ou par l'intermédiaire d'un faisceau d'antenne satellite d'un autre système. Le second signal radio comprend le signal d'interférence. Le premier et le second signal radio sont traités de manière à récupérer le signal en liaison montante satellite souhaité.
