Abstract

This article proposes a novel method for detecting coronavirus disease 2019 (COVID-19) in an underground channel using visible light communication (VLC) and machine learning (ML). We present mathematical models of COVID-19 Deoxyribose Nucleic Acid (DNA) gene transfer in regular square constellations using a CSK/QAM-based VLC system. ML algorithms are used to classify the bands present in each electrophoresis sample according to whether the band corresponds to a positive, negative, or ladder sample during the search for the optimal model. Complexity studies reveal that the square constellation (Formula presented.) yields a greater profit. Performance studies indicate that, for BER = (Formula presented.), there are gains of ?10 [dB], ?3 [dB], 3 [dB], and 5 [dB] for (Formula presented.), respectively. Based on a total of 630 COVID-19 samples, the best model is shown to be XGBoots, which demonstrated an accuracy of (Formula presented.), greater than that of the other models, and a (Formula presented.) of (Formula presented.) for positive values. © 2023 by the authors.
