Experimental Demonstration of Event-based Optical Camera Communication in Long-Range Outdoor Environment

We propose a robust demodulation scheme for optical camera communication systems using an event-based vision sensor, combining OOK with toggle demodulation and a digital phase-locked loop. This is the first report to achieve a $\mathrm{B}\mathrm{E}\mathrm{R}<{10}^{-3}$ at 200m-60kbps and 400m-30kbps in outdoor experiments.
