文摘
Multi-coded variable PPM (MC-VPPM) is a modulation technique for visible light communication (VLC), providing high data rate transmission and processing gain improvement at the receiver side. This paper proposes wavelength hopping MC-VPPM supporting multi-user communications in the vehicle-to-infrastructure (V2I) downlink and uplink scenarios of a metropolitan intelligent transportation system and analyzes its performance. By defining outdoor daylight noise and analyzing the sub-band selection effect for wavelength hopping, the communication capability of multi-user V2I downlink and uplink VLC at the daytime was investigated. The simulation results provide the required VLC transmission power for reliable data communication under the predescribed V2I scenario.
