METHOD AND APPRATUS FOR ERROR-CORRECTION IN DIMMABLE VISIBLE LIGHT COMMUNICATION SYSTEMS

摘要

An error correction method and apparatus for visible light communication are disclosed. According to an embodiment of the present invention, there is provided an error correction method for visible light communication, the method including generating an encoded message using an encoding method that is predetermined for an original message; Generating a brightness setting signal for setting a brightness of a visible light source; Calculating a puncturing ratio corresponding to the brightness setting signal; Puncturing the encoded message based on the puncturing rate; Generating a scrambled message by scrambling the punctured message; And providing the scrambled message to the visible light source.
