基于压扩变换的OFDM信号PAPR抑制方法具有实现简单、抑制效果明显的优点。对现有压扩变换PAPR抑制方法进行了分析和研究,并在此基础上,提出了一种基于均匀分布的压扩变换方法。该方法能够将任何分布的调制信号均变为均匀分布。仿真结果表明,与现有方法相比,该方法抑制PAPR的效果较为明显,且易于实现,具有较好的实用性。

The PAPR Reduction method for OFDM signal based on companding transform is easy to implement and can reduce the PAPR effectively.In this paper,the papr reduction method based on companding transform was studied and analysed.Based on this,a novel companding transform based on uniform distribution was proposed.The method can transform modulated signals to signals with uniform distribution.Simulation results show that comared with existing methods,the method can reduce PAPR effectively with low implementation complexity.
