Abstract:
This paper proposes the use of Visible Light Communication (VLC) for vehicle safety applications, creating a smart vehicle lighting system that combines the functions of illumination and signaling, communications, and positioning. The feasibility of VLC is demonstrated by employing trichromatic Red-Green-Blue (RGB) LEDs as transmitters, since they offer the possibility of Wavelength Division Multiplexing (WDM), which can greatly increase the transmission data rate, when using SiC double p-i-n receivers to encode/decode the information. Each chip, individually, is used to transmit the driving range distance and data information. An on-off code is used to transmit the data. Free space is the transmission medium. The receivers consist of two stacked amorphous a-H:SiC cells. Multiple Input Multiple Output (MIMO) architecture is used. For data transmission, two headlights based on commercially available modulated white RGB-LEDs are used. For data receiving and decoding, three a-SiC:H double pin/pin optical processors symmetrically distributed at the vehicle tail are utilized. The process of accurately encoding and decoding positioning and the design of SiC navigation system are discussed and tested. A visible multilateration method estimates the drive distance range.
