Vehicle-to-vehicle visible light communications using sub-pulse Manchester modulation

Since many cars recently adopt light emitting diode (LED) for the headlight, many researchers have extensively investigated visible light communications (VLC) for vehicle-to-vehicle (V2V) networks. In this work, we propose a novel sub-pulse Manchester modulation scheme to improve V2V network performance. Simulation results show that the proposed scheme outperforms the conventional scheme in background low frequency light environment.
