| 摘 要： | OFDM通信系统是正交多载波系统,很容易造成较高峰均功率比PAPR,从而严重降低OFDM系统的通信质量.文中分析了PAPR~]"OFDM通信性能的不利影响,探讨了改善PAPR性能的SLM.PTS概率类算法原理.基于Matlab软件构造了嵌入SLM,PTS算法模块的OFDM仿真验证系统,并提出了一种PTS改进算法.理论分析与仿真结果表明:SLM,PTS算法可有效减小PAPR OFDM通信性能的不利影响;PTS改进算法可在有效减小PAPR不利影响的前提下,减小OFDM发射机的复杂性.

| Abstract: | As an orthogonal multi carrier wave system,the OFDM communication system usually leads to a high ratio of peak to mean power,thus greatly decreases the communication quality.In this paper,the effect of PAPR for property is analyzed,principles of probability methods including SLM and PTS for improving PAPR property are discussed,the OFDM simulation system for embedded components of SLM and PTS is constructed based on MATLAB,and an improved algorithm of PTS is proposed.The results of theoretical analysis and ... |
