Performance Analysis of Filtered OFDM for 5G

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a pertinent multi-carrier modulation approach which is more immune to frequency selective fading. In 5G waveform, in order to reduce the traffic in OFDM based technology, it is significant 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. Each of the different sub-bands can be handled according to the traffic scenario. This work focusses on analyzing the performance of Filtered OFDM and OFDM in terms of Power Spectral Density (PSD) and Bit error rate (BER). The spectral efficiency in F-OFDM is increased by the reduction of out-of-band (OOB) emission. Simulation for the performance analysis of OFDM and F-OFDM in terms of PSD and BER have done in MATLAB. The working of OFDM has carried out in Verilog and the performance of all components is verified by giving different inputs.
