一种降低正交频分复用调制信号峰平比的融合方法

A Combined Scheme to Reduce the PAPR for OFDM Signals

提出了一种降低峰平比(PAPR)的融合算法,该算法在发射端对正交频分复用(OFDM)调制信号进行两次降低峰值处理,因而降低PAPR的能力远远优于常规的选择性映射法和压扩法,而该新方法传输信号的性能与压扩法相当。

This paper proposes a combined scheme to reduce twice the peak - to - average - power - ratio （PAPR） of OFDM signal so that the performance of reducing the PAPR is much better than that of the conventional SLM scheme and the companding scheme. The system performance of the proposed scheme is the same as that of the companding scheme.
