| 摘 要： | 正交频分复用(OFDM)具有较高的频谱利用率、良好的抗多径干扰能力,长期以来一直受到广泛的关注。目前,OFDM已经被公认为是下一代移动通信系统的核心技术之一,但其较高的峰值平均功率比(PAPR)却一直是制约OFDM技术发展的问题之一。如何降低OFDM系统的PAPR是目前通信领域的研究热点之一,本文对目前常用的降低PAPR方法进行了综合分析和比较,并讨论了各方法的优缺点。

Analysis of PAPR Reduction Techniques for OFDM System |
| |
| Abstract: | Due to a high ratio of frequency and good capability of repelling multipath disturbances,Orthogonal Frequency Division Multiplexing(OFDM) has always attracted much attention.Now OFDM is regarded as one of the key techniques of the next wireless communication systems.However,the high Peak-to-Average Power Ratio(PAPR) is always one of the main problems of OFDM development.Therefore,how to reduce the PAPR of OFDM signals is one research focus of communication.This paper has a comprehensive analysis and compare of the important methods to reduce PAPR,and discusses their advantages and shortages. |
