Investigating the angular distortion impact on vehicular optical camera communication (OCC) systems

Optics Express
Optical camera communication (OCC) shows promise for optical wireless communication (OWC) in vehicular networks. However, vehicle mobility-induced angular distortions hinder system throughput by degrading non-isotropic vehicular OCC channel gain. Few of the prior works have ever made a comprehensive analysis of their impact, especially based on the ...

Radio Scintillation and Gravity Wave Characteristics in the Venusian Atmosphere: Insights From Akatsuki Radio Occultation

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract We investigated the relationship between radio scintillations—short‐term fluctuations in radio signal intensity—and temperature fluctuations, both observed in vertical profiles from JAXA's Akatsuki radio occultation. Our results indicate that the radio scintillations and the temperature fluctuations are each strongly related to static ...

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.

CNN‐Based Human Detection and Identification in Indoor Optical Camera Communication Systems Using a Wearable LED Strip

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 ...
