Abstract
Visible light communication (VLC) has emerged as a promising technology for 5G and beyond networks, offering a solution for indoor wireless connectivity. This paper implements non-orthogonal multiple access (NOMA) scheme alongside multiple-input multiple-output (MIMO) technique in VLC systems to enhance the overall performance. We evaluate the impact of various power allocation techniques through three efficient and low-complexity techniques such as normalized gain difference power allocation (NGDPA), fixed power allocation (FPA) and gain ratio power allocation (GRPA) within an indoor MIMO-VLC with NOMA systems. Our investigation includes the application of the most used diversity combining techniques to improve the reliability of the received signal. Numerous simulations have been conducted to assess the system’s performance.
