Wide Field-of-View (FOV) and Bidirectional Unmanned-Aerial-Vehicle (UAV) Based Optical Wireless Communication (OWC) Using Camera

Yun-Han Chang, Chi-Wai Chow, Yu‐Heng Hong, Hao-Chung Kuo

TL;DR: This work puts forward and presents the first demonstration up to the authors’ knowledge a wide field-of-view (FOV) and bidirectional UAV-assisted OWC system using optical-camera-based under-sampled phase shift on-off keying (UPS-OOK) format.

Unmanned-aerial-vehicle (UAV)-assisted optical-wireless-communication (OWC) systems offer several advantages, including data offloading, high flexibility, high mobility, and the ability to temporarily handle unexpected data surges during catastrophic situations. However, some cha…Read more

Improving Visible Light Positioning Accuracy Using Particle Swarm Optimization (PSO) for Deep Learning Hyperparameter Updating in Received Signal Strength (RSS)-Based Convolutional Neural Network (CNN)

Chun-Ming Chang, Yuan-Zeng Lin, Chi-Wai Chow

Visible light positioning (VLP) has emerged as a promising indoor positioning technology, owing to its high accuracy and cost-effectiveness. In practical scenarios, signal attenuation, multiple light reflections, or light-deficient regions, particularly near room corners or furni…Read more
