摘　　要：主要研究了OFDM系统峰均比抑制算法中的选择性映射算法;在此基础上提出了一种能够降低系统复杂度的改进算法:TR-SLM算法;最后采用MATLAB仿真对这传统和改进的SLM算法进行仿真,并分析了这两种算法对PAPR抑制性能以及系统复杂度的影响。仿真结果表明,改进的SLM算法能很好的达到抑制PAPR目的。Selected mapping of reduction of PAPR in OFDM system is studied. A improved technique that can reduce computational complexity named TR-SLM technique, based on traditional, is proposed. Traditional and improved SLM scheme are simulated by MATLAB. And their influences on PAPR performance and computational complexity for system are analyzed. The results indicate that PAPR can be bated by the latter perfectly.
