摘　　要：目前,正交频分复用技术(OFDM)是移动通信系统的重要组成部分,然而在时域上存在高峰值平均功率比(PAPR),阻碍了其实用化。因此,加大对OFDM系统降低PAPR方法的研究具有很大的现实意义。文章阐述了OFDM技术和峰均比定义,对峰值平均功率比问题进行了分析,对几种常见的降低PAPR的方法进行了研究。Currently,orthogonal frequency division multiplexing(OFDM)technology is an important component of mobile com munications systems,but there is a peak to average power ratio(PAPR)in the time domain,which hinders its practical application.Therefore,it is of great practical significance to make further research on methods of reducing PAPR in OFDM systems.This article elaborates on the OFDM technology and the definition of PAPR,analyzes the problem of PAPR,and studies several common methods to reduce PAPR.
