| 摘要 |
The invention relates to a method for the optical transmission of data by means of an optical signal, wherein a pulse width modulation having a duty cycle as a ratio between a bright time of the optical signal and a period length of a pulse width modulation cycle is adjustable for a brightness adjustment of the optical signal. The data (DATA) to be transmitted is encoded in symbols, wherein the optical signal is modulated during the bright time (T) by a pulse amplitude modulation, wherein an amplitude of the optical signal is adjusted according to the symbol to be transmitted. A transmission quality of the optical signal is detected between a source and a sink of the optical signal. Depending on the transmission quality, a constellation of symbols designating a number of bits which can be transferred per symbol is adjusted on the source of the optical signal. |
