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.

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.In this paper, we present an optical camera communication (OCC) system utilising a deep learning for indoor communication and monitoring with wearable LED strips and cameras. Specifically, we employ the YOLOv8 object detection model, based on convolutional neural networks (CNNs), to reliably detect a yellow safety jacket equipped with an LED strip in ...

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.We experimentally demonstrate the feasibility of using up to 32‐PAM in rolling shutter based optical camera communication. A decoding algorithm focused on circumventing the hardware limitations is proposed and the performance of two different cameras is compared.
