Abstract: A visible light communication (VLC) transmitting apparatus modulates source data to an orthogonal frequency division multiplexing (OFDM) symbol according to an OFDM modulation method, inserts a diffusion code that is allocated to the VLC transmitting apparatus into a frequency axis of the OFDM symbol, converts the OFDM symbol in which the diffusion code is inserted to a visible light modulation signal, and transmits the converted visible light modulation signal. Thereby, a signal of the VLC transmitting apparatus in which a VLC receiving apparatus wants can be easily detected.

Abstract: A wireless inducement system and an auto driving apparatus for driving a vehicle and a method of driving the same are provided. The wireless inducement system includes an implanted road positioning signaler, an auto driving apparatus, and smart roadside equipment. The implanted road positioning signaler is installed in a lane and transmits a reference location wireless signal including information about location coordinates and an electric wave sending time. The auto driving apparatus grasps a location using the received reference location wireless signal and performs auto driving, and the smart roadside equipment transmits situation information about an adjacent region of the vehicle to the auto driving apparatus.
