| 摘 要： | 本文针对OFDM信号的峰值平均功率比(PAPR)问题,从瞬时功率包络出发,基于初始状态矢量的重心,得到了一种降低PAPK的OFDM子载波初始状态分布的规律．仿真结果表明,采用新的初始状态分布规律,OFDM信号PAPK大幅度降低；子载波数目加倍,OFDM信号PAPR增加不足1．0dB．

| Abstract: | In the view of PAPR in OFDM system,using envelope of instantaneous power,a rule to PAPR Reduction was studied in this paper,which was based on barycenter of initial conditions vector.From simulation,PAPR in OFDM is highly reduced,and when the number of sub-carries is doubled,the increment of PAPR is less 1.0 dB. |
