不同子载波数N的OFDM系统的PAPR性能也不同，子载波数N越大，其PAPR性能越差。给出了N=64、128、256时的常规OFDM系统的PAPR仿真曲线，同时给出了V=4时的相应子载波数的PTS-OFDM系统的PAPR性能曲线图。-N, the number of different sub-carrier OFDM PAPR performance of the system is different, the greater the number of subcarriers N, the PAPR performance is worse. When given conventional N = 64,128,256 PAPR OFDM system simulation curve, and gives a V = 4 subcarriers when the corresponding number of PTS-OFDM PAPR system performance curve.
