摘要 正交频分复用(OFDM)系统中,峰均比(PAPR)较高一直是制约系统性能的关键问题。本文分析了限幅法、选择性映射法和部分序列传输法三种降低峰均比的方法;进行了仿真及对比研究,分析总结了各自优缺点及适用条件。结果表明:三种方法都可以在一定条件下有效降低OFDM系统的PAPR。 High PAPR is a key issue to restrict the performance in OFDM system. This article analyses three methods of clipping technique, selected mapping and partial transmit sequence to reduce PAPR, verifying these methods can reduce the PAPR efficiently in OFDM by thesimulation, and comparing the advantages and disadvantages of these methods.
