Zusammenfassung: | An earth station transmitter device is arranged for generating a signal to be transmitted to a plurality of earth station receiver devices of a satellite communication system. The earth station transmitter device comprises a plurality of shapers, each arranged for shaping and encapsulating data traffic to a different subset of earth station receiver devices; obtaining for each subset a virtual carrier outputting at a virtual carrier symbol rate a plurality of virtual carrier baseband frames. A modulator includes a time slice selector arranged for receiving and storing the virtual carriers outputted by the plurality of shapers, for selecting a stored virtual carrier baseband frame from a list of allowable virtual carriers as next frame to be multiplexed on a single stream, and for assigning to the selected virtual carrier baseband frame, from a list of allowable time slice numbers. |
