| Popis: | In this study, we proposed an adaptive successive interference cancellation (SIC) technique to enhance non-orthogonal multiple access visible light communication (NOMA-VLC) and demonstrate its effectiveness using extensive simulations. NOMA-VLC is a promising technology for high-speed wireless communication, but interference from multiple users can pose a significant challenge. SIC is a technique that can help mitigate this interference. We used non-return to zero (NRZ) modulation to achieve high bit rates up to 2 Gbps and evaluated the performance using bit error rate (BER) analysis. Our simulation showed that the static power allocation (SPA) performance on the NOMA-VLC system achieved a BER value of around 10-3 for both users, using power allocation We also compared SPA against gain ratio power allocation (GRPA) and found that the performance of GRPA was not as good, with a BER value around 10-2. Our results show the effectiveness of the proposed SIC technique in enhancing the performance of NOMA-VLC. |
