Abstract
In this paper, the impact of phase change materials (PCM) as reflecting surfaces on the bit error rate (BER) performance of multiple-input multiple-output (MIMO) visible light communication (VLC) systems has been investigated. The optical properties of PCM, including absorption and reflection characteristics have been analyzed to optimize the design and functionality of PCM-based VLC systems. The current study investigates the BER performance of 4 × 4 and 8 × 8 MIMO-VLC systems using non-line of sight (NLoS) signal under varying refractive index, temperature, and incidence angle conditions. Additionally, different types of PCM has been assessed, such as organic compounds, salt hydrates, and paraffin wax, to determine their suitability for implementation in MIMO-VLC systems.
