Research on the performance of OFDM and similar modulation modes

In this paper, the performance of OFDM is simulated and evaluated from various dimensions by comparing with similar modulation methods. OFDM is compared with F-OFDM (filtered OFDM), FBMC (Filter Bank multi-carrier modulation) and UFMC(Universal Filtered multi-carrier modulation).Firstly, the concept and background of each modulation are introduced, and then the corresponding parameters of OFDM modulation are simulated and compared . Then the model of the channel-free receiver is built and simulated. Finally, the UFMC has the characteristics of high spectral efficiency, large bandwidth and sidelobe suppression .
