Inter-vehicle communication apparatus and method using visible light communication
Abstract:
The present invention relates to an inter-vehicle communication apparatus and method using visible light communication. The inter-vehicle communication apparatus using visible light communication includes a spreading code application unit for applying a spreading code to transmission data desired to be transmitted, and a transmission unit for generating a transmission frame based on the transmission data to which the spreading code is applied, and transmitting the transmission frame via a lighting lamp of a vehicle. The transmission frame includes a preamble field required to synchronize the transmission frame, a data field required to transmit the transmission data, and a position field required to provide hopping information of the transmission data.
