摘要

本文针对正交频分复用（ＯＦＤＭ）系统提出了一种新的非常有效的降低其峰值平均功率比的方法．它基于求解ＯＦＤＭ系统部分传输序列圆周移位的最优和，同以前的基于部分传输序列最优组合的方法相比，在同样的条件下针对不同的ＯＦＤＭ系统，新算法的性能均有不同程度的提高，在实际应用中可以完全取代老的算法．

Abstract

This paper proposes a very effective peak to average power ratio reduction scheme for orthogonal frequency division multiplexing（OFDM） systems by optimum summing of circular shifting of partial transmit sequences.Compared with the old method based on optimum combination of partial transmit sequences

the new method achieves the better performance in different degree for different OFDM systems under the same conditions.So the new method can be used to replace the old one in practice at all.
