PAPR Reduction of UFMC Communication for 5G Mobile System
UFMC using multi-carrier has received quite big attention as a modulation technique for 5 generation mobile communication. But these modulation technologies have high PAPR characteristic due to the overlapping of multi carrier signal. This paper design DFT-s-UFMC system to overcome the PAPR problem which modulation techniques for 5 generation mobile communication have and evaluate PAPR performance. After designing OFDM, UFMC, DFT-s-OFDM system and DFT-s-UFMC, performed checking the signal characteristics and evaluating and comparative analysis PAPR performance for simulation. As a result of simulation, PAPR performance of OFDM and UFMC was found to be improved each 2.7 dB, 2,8 dB when you apply DFT spreading technique in UFMC like DFT-s-OFDM.
