Evaluation of Pulse-Shaped Waveform Modulation for Event Camera-Based OCC Systems

Abstract

This study introduces an event camera-based optical camera communication system utilising pulse-shaped waveform modulation leveraging the camera's high temporal resolution and sensitivity. The proposed scheme demonstrates reliable performance under controlled indoor conditions with a fixed transmitter–receiver distance, achieving bit error rate values below 3.13 $\times$ 10${}^{-3}$ at data rates of 100 bit/s with mid-range receiver bias sensitivity and mid-high transmitter illumination. Although the experiments tested only four symbols, the flexible design supports higher-order modulation, which has the potential for increased data rates and more efficient bandwidth utilisation.
