Summary:
In order to satisfy requirements of 5G mobile communication, researches on new waveform based on multi-carrier are being carried out. In this paper, we describe OFDM, UFMC, FBMC, and W-OFDM. And then, we evaluate and analyze spectrum characteristics of these system under the nonlinear HPA environment. As simulation results, FBMC has the lowest OOB power under the linear HPA condition. But, OOB power levels of UFMC, FBMC, and W-OFDM are similar under the nonlinear HPA environment. In real implementation, HPA has nonlinear characteristic. Therefore, W-OFDM technique is more advantageous because W-OFDM system has low-complexity and requires simple processing
