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

Electronics Letters, Volume 61, Issue 1, January/December 2025.
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.
