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…

TL;DR: This paper proposes a high-reliability MIMO VLC system architecture employing spatially separated receiver units, where each unit utilizes an analog-aggregated angular diversity receiver with a multi-directional photoresistor array, and introduces a current mirror-based analog pre-conditioning circuit.
Visible light communication (VLC) has emerged as a promising technology for next-generation wireless communication systems, particularly for indoor positioning and massive Internet of Things (IoT) networks, due to its immunity to electromagnetic interference and high directivity.…
