¿µ¹®³»¿ë¿ä¾à In the standard, the receiver PHY layer which corresponds to the reference architecture of transmitter and receiver PHY using Color RS-OFDM modulation for LED panel and light based image sensor communication is defined, and the main functions of receiver PHY layer and the basic elements in receiver PHY layer are described. Also, the considerations for each element function are described. The modulation scheme in time domain Color RS-OFDM is supported by combining Color Shift Keying scheme and RS-OFDM scheme.
