| Abstract |
In our increasingly connected world, communication is vital, and innovative technologies are continuously transforming how we transmit information. One such groundbreaking development is the MIMO-based visible light communication (VLC) link. MIMO-based communication links are increasingly used for Smart City applications such as streetlights, traffic signals, and parking meters. MIMO-based communication links can provide efficient and reliable communication. However, the performance of these links can be affected at different weather conditions. To ensure reliable communication under different weather conditions, appropriate measures need to be taken, such as selecting the appropriate modulation technique, adjusting the transmission power and using error-correcting codes. In this paper, the performance of a MIMO-based visible light communication system is assessed using three distinct digital modulation techniques with various weather conditions including sunny weather, haze, light rain, moderate rain, and foggy conditions. It can be seen from the results that among all modulation schemes, fog has the most detrimental effect on the performance of the MIMO-VLC system. The system operates optimally within a range of up to 1 km. However, beyond this range, both the Q-Factor and BER values deteriorate. The findings indicate that among the three modulation schemes, ASK exhibits the most favourable performance across distinct weather scenarios. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024. |
