Abstract:
(DE) Die Erfindung betrifft ein Verfahren für die redundante Übertragung von Daten mittels lichtbasierter Kommunikation, wobei ein zu übertragender Datenstrom in Symbole umgewandelt wird. Dann wird dieser Datenstrom von bipolaren Symbole in mehrere Teildatenströme mit z.B. unipolar positiven Symbolen umgewandelt. Schließlich werden diese Teildatenströme in mehrere teilredundante Signale umgewandelt, die dann über mehrere lichtbasierte Kanäle zum Empfänger übertragen werden. Dort werden die empfangenen Signale wieder analog zum Versenden rückumgewandelt, um am Schluss wieder den originalen Datenstrom zu erhalten.
(EN) The invention relates to a method for the redundant transmission of data by means of light-based communication, wherein a data stream to be transmitted is converted into symbols. This data stream is then converted from bipolar symbols into multiple partial data streams having e.g. unipolar-positive symbols. Finally, these partial data streams are converted into multiple semi-redundant signals that are then transmitted to the receiver via multiple light-based channels. In the receiver, the received signals are converted back again analogously to when they were sent, in order ultimately to obtain the original data stream again.
(FR) L'invention concerne un procédé de transmission redondante de données par communication basée sur la lumière, un flux de données à transmettre étant converti en symboles. Ce flux de données de symboles bipolaires est ensuite converti en plusieurs flux de données partiels comprenant par exemple des symboles positifs unipolaires. Enfin, ces flux de données partiels sont convertis en plusieurs signaux partiellement redondants qui sont ensuite transmis au récepteur par l'intermédiaire de plusieurs canaux à base de lumière. Les signaux reçus sont de nouveau convertis en retour de manière analogique pour l'émission afin d'obtenir à nouveau le flux de données original.
