This project will design and prototype a VLC system based on the platform OpenVLC (), which is an open source, flexible and low-cost VLC platform. A major objective of this project is to understand how a pair of outdoor VLC transmitter and receiver should adapt in order to accommodate different modulation schemes and weather conditions. Towards this objective, the following two areas will be optimized: Adaptive Coding and Modulation (ACM) and Constellation Shaping.

These must be set to allow the magnets when rotating (at a 29” tire at 10mph it will rotate 116 RPMs) to give the coil a gap to allow them to obtain maximum power output. As the coils obtain this power output it will be in an AC mode.

The design needs to follow PCB design standards and be validated for heat management and general safety. An estimate of heat dedication required would be a plus. If modifying already available PCB designs, the design standards still need to be followed so that the design is UL compliant.
