This paper describes the basic principles of OFDM(Orthogonal Frequency Division Multiplexing), FBMC(Filter Bank Multi-Carrier), UFMC(Universal Filtered Multi-Carrier), GFDM(Generalized frequency division multiplexing) and F-OFDM(Filtered-Orthogonal Frequency Division Multiplexing) in detail, and compares the performance characteristics and computational complexity of the five new modulation technologies. Studies have shown that, except for OFDM, the other four types of out-of-band leakage all are low, because FBMC and UFMC do not use CP, so they have high time-frequency efficiency, but the complexity is also increased accordingly. GFDM is a kind of independent block modulation with flexible frame structure, good robustness, lower complexity and good applicability. F-OFDM has fast sidelobe attenuation and high spectral efficiency, which can greatly suppress adjacent band interference through sub-band filter, meeting the needs of 5G rich service scenarios.
