Performance Analysis of OFDM,UFMC and FBMC in Optical Wire Communication

Abstract

Optical Wireless Communications have become an essential research topic due to their potential spectrum efficiency. Nowadays, OWC evaluates many applications such as internet of things (IoT), visible light communication (VLC), and light fidelity (Li-Fi). OFDMA, FBMC, UFMC, recently used in 4G and 5G. This work is concentrated on providing a detailed study for the new modulation schemes. This article compared between BER, PAPR, spectral Density, and spectral efficiency of FBMC, UFMC, and OFDM modulation techniques to analyze the merits of them. The simulation results show that OFDMA has a higher BER, lower PAPR, compared to FBMC while FBMC has greater spectral efficiency and better performance of spectral density which makes it the optimum modulation schema among the rest. Furthermore, UFMC produces better results than OFDM and eliminates the complexity of FBMC.
