PAPR improvement with Binomial filter based FBMC was 1.16 dB at 64-QAM and 1.1 dB at 256-QAM. With Binomial filter based FBMC, OOBE improvement was 19.7 dB and BER improvement was 0.03 at 0 dB SNR. With FPBF based OFDM, PSD improvement was 97.5 dB, and BER improvement was 0.07 at 0 dB SNR. Proposed novel prototype filters for FBMC, Filtered-OFDM, and UFMC are respectively Binomial filter and Fractional Powered Binomial Filter (FPBF). The novel and better PFs, described in the paper, were proposed first time by the authors and his research group. This paper compares different performance parameters of Filtered-OFDM, FBMC, and UFMC using existing proto-type filters and novel proto-type filters. Areas of improvement are Power Spectral Density (PSD), Bit Error Rate (BER), Signal to Interference Ratio (SIR), Doppler Diversity, and Peak to Average Power Ratio (PAPR).

NR waveforms require performance improvement when high reliability, massive connectivity, lower power consumption, and time-critical applications are required. Some of the NR filtering techniques are Filtered-OFDM (F-OFDM), Filter Bank Multi-Carrier (FBMC), and Universal Filtered Multi-Carrier (UFMC).

NR waveforms can adapt in a better way to different channel conditions. Prototype Filter (PF) of NR plays a vital role in performance improvement of wireless systems. NR is the radio interface technology proposed by the 3 rd Generation Partnership Project (3GPP) for 5G. New Radio (NR) waveforms of existing wireless communication systems need further improvement in order to support future wireless communications.
