Position Estimation Method Using RGB Values of LED Colour Temperature in a Fuzzy Logic System

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
This study proposes a novel LED‐based positioning system that estimates two‐dimensional position by analysing the chromaticity and frequency components (via FFT) of indoor lighting in tunnel environments where GPS signals are blocked. Experimental results demonstrate that the proposed method achieves reliable positioning accuracy within 5 cm in ...

Hybrid VLC–IR Communication System With Beam‐Steered Uplink and Turbo Coding Under Mobility

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
This paper presents a hybrid VLC–IR communication system integrating a beam‐steered infrared uplink with Turbo coding for reliable indoor optical wireless links. The proposed architecture achieves BER below 10−3 at 10 dB SNR and maintains stable coverage under NLOS conditions through adaptive beam steering.
