Description
Quantum technology is opening new horizons in next-generation wireless communication, with Visible Light Communication (VLC) emerging as a strong candidate to complement and extend traditional systems. While VLC offers high data rates and efficient spectrum utilization, it faces persistent challenges, including security limitations, high Peak-to-Average Power Ratio (PAPR), and LED nonlinearity.
In this work, we propose a Hybrid Quantum–VLC (HQVLC) system that integrates quantum communication principles with the Asymmetrically Clipped Optical OFDM (ASCO-OFDM) modulation scheme. This approach ensures not only secure and robust data transmission, but also high-rate and spectrum-efficient communication. To further optimize performance, we incorporate companding and precoding techniques to mitigate the effects of PAPR and LED nonlinearity, thereby achieving a more power-efficient system.
The result is a VLC framework that delivers both quantum-enhanced security and optimized power efficiency—a dual advantage that positions HQVLC as a promising step towards the future of secure and high-performance wireless communication systems.
