Fast Detection and Tracking of a Moving Transmitter via Visible Light Communication Link

We propose a passive detection and tracking methodology for CamCom receivers in intelligent transport systems. The implemented architecture maximizes the data rate and can maintain a BER of 1.9 × 10
^-4
while passively detecting and tracking the moving transmitter undergoing worst-case road vibration of 30.6 mm/s. The proposed methodology is also independent of the size and shape of the transmitter and thus finds promising application in intelligent transport.
