Abstract

Visible Light Communication (VLC) has gained recognition as a potential technology for high-speed indoor wireless communication and 6-G applications. Filter bank multicarrier (FBMC) is a multi-carrier modulation that provides better spectral efficiency and is regarded as a promising scheme for the next generation of wireless communication and an alternative to orthogonal frequency division modulation (OFDM). However, the use of a multi-light-emitting diode (LED) array in indoor VLC leads to multipath dispersion, causing the issue of intersymbol interference (ISI) that degrades system performance and produces large delays and a high bit-error rate (BER). Therefore, this research proposed a post-equalization technique using an artificial neural network (ANN) equalizer to enhance the system’s overall performance and BER. The result shows that channel equalization using (ANN) equalizer upgraded the system performance by 49.9% in high signal-to-noise ratio (SNR), and a lower BER is achieved compared to the conventional VLC-FBMC system without the equalizer.
