الملخص:<p dir="ltr">In this article, Intelligent Reflecting Surfaces (IRS) are used for Non Orthogonal Multiple Access (NOMA) in hybrid Radio Frequency (RF) Visible Light Communications (VLC). The source broadcasts the symbols of <i>K</i> users. The broadcasted signal by the source is reflected by IRS on RF link to reach the relay node <i>R</i> with the same phase. Relay node detects the symbols of <i>K</i> users using Interference Cancelation (IC). Then, relay nodes broadcasts the symbols of <i>K</i> users on VLC link. We show that NOMA using IRS for hybrid RF/VLC offers 12–18 dB gain versus conventional hybrid RF/VLC without reflectors for <i>N=32</i>,168 reflectors. The main advantage of the paper is to enhance the throughput of RF/VLC systems using IRS. The main limitation of the paper is that the results are not valid when energy harvesting is performed.</p><h2>Other Information</h2><p dir="ltr">Published in: Wireless Personal Communications<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s11277-024-11130-2" target="_blank">https://dx.doi.org/10.1007/s11277-024-11130-2</a></p>
