摘要

为了降低正交频分复用系统中 SLM 算法的峰均功率比，减少边带信息传输，提高频谱利用率，首先提出基于转移矩阵和混沌序列的TL-SLM算法。TL-SLM算法有效减少了边带信息的传输，但PA P R的降低幅度有限。因此，进一步提出基于旋转向量的改进TL-SLM算法，即TR-SLM算法，该算法通过旋转向量的引入，产生更多的时域备选信号，达到进一步降低PA P R的目的。性能分析表明，虽然TL-SLM算法和TR-SLM算法少量增加了系统的复杂度，但PAPR性能得到了有效改善，而且较大幅度地减少了边带信息的传输。

Abstract

In order to reduce the peak to average power ratio (PAPR) of the conventional selective mapping (SLM) algorithm

decrease the transmission of side-band information

and improve the spectral efficiency in the orthogonal frequency division multiplexing (OFDM) system

the TL-SLM algorithm based on the conversion matrix and the chaotic sequence was proposed firstly.Although the TL-SLM algorithm could effectively decrease the transmission of side-band information

the reduction of PA P R was limited.To solve this problem

an improved TL-SLM algorithm based on the rotation vector was proposed

which was the TR-SLM algorithm.TR-SLM algorithm introduced the rotation vector to generate more time-domain alternative signals to further reducing the PA P R.The performance analysis shows that although the TL-SLM algorithm and the TR-SLM algorithm increase the complexity a little

the PA P R performance is effectively improved and the transmission of side-band information is greatly reduced.
