摘要
An optical signal transmission method according to an embodiment of the present disclosure is an optical signal transmission method in which a processor performs at least a portion of each step, and includes receiving a data stream, dividing at least a portion of the data stream into three channels, and separating A step of generating an FSK-modulated signal by modulating each of the data streams in an M-FSK (Mary-Frequency Shift Keying) method. For the same bit code, frequencies mapped to each channel are different, and a plurality of modulated data streams in three channels are each different. synthesizing the FSK modulated signal of , generating a color modulated signal based on a preset bit-color mapping table, and transmitting the color modulated signal by controlling a light source of the same optical channel based on the color modulated signal. can
