¿µ¹®³»¿ë¿ä¾à | In the standard, the receiver PHY layer which corresponds to the reference architecture of transmitter and receiver PHY using Wavelength Division Multiplexing (WDM) 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 Wavelength Division Multiplexing (WDM) modulation is supported by combining Wavelength Division Multiplexing (WDM) modulation and On-Off Keying. By applying WDM, we can apply for multi-users instead of single user in the conventional On-Off Keying scheme. | ||
