Abstract
Visible Light Communication (VLC) presents a promising technology for future wireless communication systems, offering a high-speed and secure alternative to traditional radio frequency (RF) based wireless systems. To enhance VLC performance, the Orthogonal Frequency Division Multiplexing (OFDM) technique has been employed. OFDM's high spectral efficiency and robustness to multipath interference make it well-suited for mitigating inter-symbol interference (ISI) and maximizing spectral efficiency. This study explores the OFDM-VLC system under OptiSystem software, utilizing a high-efficiency Perovskite-based Light-Emitting Diode (LED). Specifically, the investigation emphasizes the SrLa2Al2O7:Er3+ LED, which exhibits high luminescence efficiency with a Quantum Efficiency (QE) of approximately 68.33%. The impact of the number of OFDM subcarriers and the SrLa2Al2O7:Er3+ LED's characteristics on system performance are thoroughly analyzed over various channel ranges and bit rates. To evaluate the system's efficacy, the performance of the proposed OFDM-VLC system was rigorously assessed using rigorous performance metrics, including Bit-Error Rate (BER) and constellation diagrams. The findings unequivocally demonstrate the substantial enhancement in communication reliability and efficiency achieved by the proposed OFDM-VLC system based on SrLa2Al2O7:Er3+ LED.
