| 摘 要： | 正交频分复用(OFDM)系统的主要缺点是峰均功率比(PAPR),它的增大严重地降低了发射机中高功率放大器(HPA)的效率。本文在传统PTS算法的基础上,综合分析了降低PAPR的各种次优化PTS算法,包括:IPTS算法、APTS算法、SO-PTS算法、DL-PTS算法、SA-PTS算法和E-PTS算法等。并对各算法的流程、复杂度和性能进行了对比。最后进行了性能仿真,提出了次优化PTS的发展方向。

| Abstract: | The main drawback of Orthogonal Frequency Division Multiplexing(OFDM) systems is the high peak-to-average power ratio(PAPR),which significantly reduces the efficiency of the transmit high power amplifier(HPA).This paper is based on the traditional PTS algorithm.Various sub-optimize PTS algorithm for reducing PAPR are analysed synthetically,including: IPTS,APTS,SO-PTS,DL-PTS,SA-PTS and E-PTS algorithm,etc..And has carried on the contrast to the procedure,complexity and performance of every algorithm.It Carries on performance simulation finally,proposes developing direction of sub-optimize PTS algorithm. |
