Multirate Filtered OFDM Waveform for 5G and Beyond Wireless Communication Systems

F-OFDM has better performance and is more suitable for low power low cost IoT applications in 5G/6G. Normal F-OFDM suffers from high computational complexity when compared with multirate F-OFDM. Performance analysis based on mathematical modelling and Matlab simulations of multirate F-OFDM has been carried out. Matlab simulations and mathematical modelling has been carried out to analyze effect of ACI, ISI, and ICI. It has been observed that multirate filtered OFDM has better performance than simple filtered OFDM. The multirate F-OFDM has reduced complexity than normal F-OFDM and is suitable for the next generation communication systems.
