Abstract:
Due to the general, worldwide need for communication, Visible Light Communication (VLC) has become a research topic today. In comparison to other wireless technologies (such as Wi-Fi), this technology combines lighting and communication, enabling high data rates and reliability. In this paper VLC is used to establish different optical communication links for bidirectional communication between infrastructures and vehicles, namely Infrastructure-To-Vehicle (I2V) and Vehicle-To-Infrastructure (V2I). VLC is used to provide guidance and management services for autonomous robot navigation inside an automated warehouse. Specific coding schemes are used in each optical link. The I2V link uses RGB white LEDs to simultaneously modulate the emitters embedded in each LED, allowing wavelength division multiplexing of optical signals transmitted via this link. The detection is based on an a-SiC:H pin-pin photodetector with tunable sensitivity in the visible range. The impact of parity check bits on bit error rate is discussed for different indoor communication scenarios.
