Title (EN) APPROACHES FOR IMPROVED FREQUENCY REUSE EFFICIENCY AND INTERFERENCE AVOIDANCE FOR A MULTI-BEAM SATELLITE COMMUNICATIONS NETWORK
(FR) APPROCHES POUR UNE EFFICACITÉ DE RÉUTILISATION DE FRÉQUENCE AMÉLIORÉE ET UN ÉVITEMENT D'INTERFÉRENCE POUR UN RÉSEAU DE COMMUNICATION PAR SATELLITE À FAISCEAUX MULTIPLES
Abstract:
(EN) An RF communications transmitter system comprising a processor, a switch and a plurality of feedhorns. The switch is configured to receive a feed signal of a frequency bandwidth. The processor is configured to control the switch to provide the feed signal to each of at least two of the feedhorns for a respective time period. Each of the at least two feedhorns is configured to generate a beam during the respective time period that the feed signal is provided thereto, wherein the beam is formed based on the feed signal and is transmitted to cover a geographic area of the Earth. The formation and transmission of the beams by the feedhorns is controlled by the processor to provide a time-based allocation of bandwidth amongst the beams based on the time period that the feed signal is provided to each of the feedhorns and a respective frequency/polarization reuse scheme.
(FR) L'invention concerne un système émetteur de communications RF comprenant un processeur, un commutateur et une pluralité de cornets d'alimentation. Le commutateur est configuré pour recevoir un signal d'alimentation d'une bande passante de fréquence. Le processeur est configuré pour commander le commutateur pour fournir le signal d'alimentation à chacun d'au moins deux des cornets d'alimentation pendant une période de temps respective. Chacun des au moins deux cornets d'alimentation est configuré pour générer un faisceau pendant la période de temps respective selon laquelle le signal d'alimentation est fourni à celui-ci, le faisceau étant formé sur la base du signal d'alimentation et étant transmis pour couvrir une zone géographique de la terre. La formation et la transmission des faisceaux par les cornets d'alimentation sont commandées par le processeur pour fournir une allocation temporelle de largeur de bande parmi les faisceaux sur la base de la période de temps que le signal d'alimentation est fourni à chacun des cornets d'alimentation et un schéma de réutilisation de fréquence/polarisation respectif.
