  • Communication method and device in optical camera communication system
    Patent number: 11979193
    Abstract: A method of modulating an optical camera communication (OCC) signal by an OCC transmission node in an OCC system includes acquiring a binary data signal, grouping the binary data signal for every k bits to convert the binary data signal into a global phase shift signal having an integer value from 0 to M?1 (=2k?1), generating a data signal group by mapping the global phase shift signal to first to Mth mapping sequences in the form of an n*M/2-bit sequence based on a preset symbol group mapping table, generating a pulse wave signal by modulating the data signal group, and blinking each of a plurality of light sources included in the OCC transmission node according to the pulse wave signal. Accordingly, performance of the communication system may be improved.
