Objectives: To design a novel waveform for 5G communications with less Peak to Average Power Ratio and high Spectral efficiency Methods/Statistical Analysis: In this paper, Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multicarrier (FBMC)and Universal Filtered Multi-Carrier (UFMC) are compared and PAPR of these techniques is analyzed by applying different subcarriers and modulation techniques. Findings: The spectral efficiency is poor in OFDM due to the presence of cyclic prefix and the efficiency can be improved by FBMC and UFMC. The use of separate filters for individual subcarriers eliminates the cyclic prefix and an increase in the sub carriers reduces the PAPR further. The PAPR varies according to the modulation techniques used. Application/Improvements: UFMC is a better waveform technique for 5G communication when compare to OFDM and FBMC which will have less PAPR and the PAPR is further reduced by applying the optimization techniques.
Keywords: FBMC, OFDM, PAPR, UFMC
