Experimental demonstrations of high‐accuracy 3D/2D indoor visible light positioning using imaging multiple‐input multiple‐output receivers and artificial neural networks

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
The paper proposes and demonstrates a high‐precision indoor 2D and 3D visible light positioning system using an imaging MIMO configuration with supervised ANN, achieving positioning accuracies of 3.7 mm (2D) and 51 mm (3D) experimentally. A simulation model verifies the results and optimises the system, improving accuracies to 2 mm (2D) and 14.7 mm (3D)

Data Transmission via Visible Light Communication (VLC) Technique

International Journal of Innovative Research in Science, Engineering and Technology, 2016
2 ABSTRACT: Light Emitting Diodes are set to penetrate many areas of everyday life. An interesting property of these devices in addition to their lightening capabilities , is that they can also be utilised for data transmissions as well. LED's require low power for their operation and have very high switching speeds.

Real-time white-light phosphor-LED visible light communication (VLC) with compact size

Optics Express, 2013
In this demonstration, we first demonstrate a real-time phosphor-LED visible light communication (VLC) system with 37 Mbit/s total throughput under a 1.5 m free space transmission length. The transmitter and receiver modules are compact size. Utilizing our proposed pre-equalization technology, the ~1 MHz bandwidth of phosphor LED could be extended to ...

Deep Learning Based Design of Binary Signalling for Optical Wireless Communication Systems With 2D Receiver

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
We apply a deep learning (DL) technique to binary signalling design for optical wireless communication (OWC) system with a 2D LED transmitter array and an arrayed 2D receiver. It is demonstrated that the DL‐based signalling design algorithm is feasible for OWC system, considering physical channel effect. ABSTRACT Recently, deep learning (DL) techniques
