Abstract
This paper analyzed the PHY technology of IEEE 802.15.7 which is a technology trend and international standard of the LED-based VLC communication system. Also, the study analyzed the complexity of the system as well as the reception performance in a visible light wireless channel environment by analyzing detailed technology of PHY I mode and designing the RS code and block interleaver. According to the result, concerning PHY I which is operated in a single mode, it was confirmed that the complexity in designing the system was higher compared with an environment of the transmission of a short massage. Also it was confirmed that in a multi-path visible light channel environment, the reception SNR=1.5dB was required additionally.
