BER Performance Analysis of OFDM, W-OFDM and F-OFDM for 5G Wireless Communications

Abstract

Orthogonal Frequency Division Multiplexing OFDM is a pertinent multi-carrier modulation approach that is more immune to frequency selective fading In the 5G waveform in order to reduce the traffic in OFDM based on technology it is important to re-size the bandwidth Consequently a spectrally localized waveform technology called Filtered Orthogonal Frequency Division Multiplexing F-OFDM which is primarily an approach to sub-band based filtering is introduced Windowed-OFDM W-OFDM which is basically a classical OFDM scheme where each symbol is windowed and overlapped in the time domain Each of the different subbands can be processed according to the traffic scenario
