Performance Analysis of OFDM and FBMC

Abstract

The purpose of this article is to compare the proposed 5G modulation techniques FBMC against OFDM which is the modulation technique used in 4G communications. In this article, we compare Spectral Density, Spectral Efficiency, PAPR, BER of FBMC and OFDM modulation techniques to analyze the merits of them. The simulation results show that FBMC has the lower BER, higher PAPR, greater Spectral Efficiency (if the burst is larger) and better performance of Spectral Density compared to OFDM modulation.
