Abstract

Erfindungsgemäß soll eine verbesserte Satelliten-Sendeeinheit bereitgestellt werden, die ein effizientes Dekodieren von ausgesandten Datenströmen ermöglicht.According to the invention, an improved satellite transmission unit is provided which enables efficient decoding of transmitted data streams.

Diese Aufgabe wird durch eine Satelliten-Sendeeinheit gelöst, die umfasst:
- eine Paketaufteilungseinrichtung (12) zur Erzeugung von Nutzdatenpaketen (4, 4', 4") mit einer vorzugsweise konstanten Nutzdatenpaketlänge aus einem Eingangsdatenstrom (1);
- eine Piloterzeugungseinrichtung (17) zur Erzeugung von Pilotdatenpaketen (7 - 7"');
- eine Kopfdatenerzeugungseinrichtung (15) zur Erzeugung von Kopfdatenpaketen (5, 5', 5") mit Informationen bezüglich des Eingangsdatenstroms (1), insbesondere bezüglich des verwendeten Modulationsverfahren und/oder Codierungsverfahren;
- eine Verknüpfungseinrichtung (18) zum Zusammenfügen der Nutzdatenpakete (4, 4', 4"), des Kopfdatenpakets (5, 5', 5") und der Pilotdatenpakete (7 - 7"') zu einem Ausgangsdatenstrom (3), wobei mindestens ein Paar von Pilotdatenpaketen (7 - 7"') eine Vielzahl von Nutzdatenpaketen (4, 4', 4") und mindestens ein Kopfdatenpaket (5, 5', 5") umschließt.

Figure imgaf001
This object is achieved by a satellite transmission unit which comprises:
- A packet distribution device (12) for generating user data packets (4, 4 ', 4 ") with a preferably constant payload packet length from an input data stream (1);
- A pilot generating means (17) for generating pilot data packets (7 - 7 "');
- A header data generating means (15) for generating header data packets (5, 5 ', 5 ") with information regarding the input data stream (1), in particular with respect to the modulation method and / or coding method used;
- A linking device (18) for combining the user data packets (4, 4 ', 4 "), the header data packet (5, 5', 5") and the pilot data packets (7 - 7 "') to an output data stream (3), wherein at least a pair of pilot data packets (7 - 7 "') encloses a plurality of payload data packets (4, 4', 4") and at least one header data packet (5, 5 ', 5 ").
