Overview

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 $^{-3}$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. This study presents an event camera‐based optical camera communication (OCC) system using a novel pulse‐shaped waveform modulation to exploit the camera's high temporal resolution and sensitivity. The system achieves error‐free links under controlled indoor conditions, with a bit error rate (BER) below 3.13 × $\\times$10−3 $^{-3}$at data rates of 100 Hz. Its flexible design supports higher‐order modulation, offering potential for increased data rates and efficient bandwidth utilisation
