¿µ¹®³»¿ë¿ä¾à In the standard, the receiver PHY layer which corresponds to the reference architecture of transmitter and receiver PHY using Color C-OOK 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 C-OOK is supported by combining Color Shift Keying scheme and Camera On-Off Keying. The more detail of Color C-OOK will be show in below. Besides that, the structure of color C-OOK will be shown to highlight the advantages of this scheme.
