¿µ¹®³»¿ë¿ä¾à In the standard, the receiver PHY layer which corresponds to the reference architecture of transmitter and receiver PHY using hybrid S2-PSK and DSM-PSK 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 hybrid S2-PSK and DSM-PSK is supported by combining S2-PSK and DSM-PSK with single camera in the receiver side.
