摘要

Visible light communications (VLC) has attracted increased attention in wireless communications research. VLC is safe for human health, secure, energy-efficient, and operates within the visible light spectrum, thereby circumventing the limitations of RF communication bandwidth. In this article, the authors improve the complexity of the VLC systems. A novel unipolar receiver for the traditional asymmetrically clipped absolute value optical OFDM (AAO-OFDM) system is proposed, mathematically analyzed, and compared with existing schemes, demonstrating a high data-rate ratio of 45% and a favorable bit error rate (BER) relative to previous systems. The proposed receiver decreases system complexity by 16.67%. A comprehensive study, simulation outcomes, and a comparison of the suggested system with current systems are provided, along with a succinct evaluation of existing methodologies.
