The approach addresses key challenges in visible light communication, including pulse distortion and sunlight interference.

Scientists have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light.

The team achieved reliable outdoor VLC at data rates of up to 3.48 Mbit/s over distances of several meters by implementing a newly designed 8B13B coding scheme on an FPGA and interfacing it with a Raspberry Pi.

The approach addresses key challenges in VLC, including pulse distortion and sunlight interference, and offers a practical path toward intelligent transportation system (ITS) applications.
