Abstract

Um bei einer digitalen Datenübertragung eine hohe Bandbreiteneffizienz und geringe Bit- und Messagefehlerwahrscheinlichkeit zu erzielen, ist ein System (1) mit zugehörigen Verfahren und Einrichtungen vorgesehen, bei dem keine Träger- und Taktsynchronisation erforderlich ist. Es wird ausgehend von einer Blocksynchronisation eine digitale Mehrträgerübertragung mit Codierung und Decodierung durchgeführt, wobei bei der Trägermodulation die Belegung der Subträger in Richtung der Subträger, also in Frequenzrichtung, differentiell codiert erfolgt.
