“…OOK is a simple and widely used modulation technique, but it can suffer from low spectral efficiency and high error rates, especially in noise and interference. The use of NRZ coding in this study helps to increase the bit rate up to 2 Gbps, which is twice the bit rate compared to the previous research (Putri, Hambali, and Pamukti 2019).…”

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 α1=0.7 and α2=0.3. 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.

“…Since it is practically impossible to increase the size of the photodiode itself without influencing the resulting bandwidth, many teams tend to develop optical concentrators. Putri et al presented their own concentrator, which managed to improve the communication coverage of an on-off keying (OOK)based system by approximately 15 to 55% [51]. A fluorescent concentrator can be even used to implement a MIMO system, as presented by Mulyawan et al [52].…”

This paper focuses on a channel feed-forward software defined equalization (FSDE) of visible light communication (VLC) multistate quadrature amplitude modulation (M-QAM) based system, implemented in the LabVIEW programming environment. A highly modular platform is introduced; the whole experiment is simulated in software and then thoroughly explored and analyzed during practical measurements in the laboratory, simulating real-world situations. The whole platform is based on modified National Instruments software defined radios (NI SDR) and a commercially available Philips light source, often used in Czech government institutions. Three FSDE algorithms were tested: least mean squares (LMS), normalized least mean squares (NLMS), and QR decomposition based RLS (QR-RLS). Based on measurements, QR-RLS provides the best results, improving measured values by up to 10%. The experiments also show that the simulated results are very similar to real measurements, thus proving the validity of the chosen approach. The whole platform manages to improve measured data simply by making changes to the software side of the testing prototype.
