Summary:
Recently, many researches on new waveforms have been carried out. UFMC and FBMC technique are famous as a new waveform for 5G. Similar to OFDM system, these techniques use multi-carrier. So, these systems have high PAPR, which can cause nonlinear distortion and OOB power increase because of the nonlinear HPA. In this paper, we have focused on spectrum characteristic analysis and BER performance evaluation of FBMC and UFMC system under the effect of nonlinear HPA. As simulation results, it is confirmed that OOB power of each system increases, and OOB power increase of FBMC system is the biggest. Additionally, we have confirmed that performance of every system is degraded by strength of HPA nonlinearity, and every system needs the PAPR reduction method for the nonlinear distortion compensation and power saving, even though it would be more complicated.
