OFDM系统中降低峰均功率比的研究
<span id="LbZY">正交频分复用技术（Orthogonal Frequency Division Multiplexing， OFDM）非常适合高速通信系统，但存在高峰均功率比（PAPR）的问题。对OFDM系统中如何降低PARR的问题进行了研究，讨论了降低PAPR的主要方法，重点分析了选择性映射法（SLM），并在此基础上提出了一种基于预编码矩阵的改进算法，最后通过matlab进行了算法

一种降低OFDM系统PAPR联合算法的研究
<span id="LbZY">选择映射法（SLM）和概率类算法都可以降低OFDM （Orthogonal Frequency Division Multiplexing）系统的PAPR（Peak to Average Power Ratio），传统SLM算法自身较为复杂，但由于其优良的性能，弃之可惜。研究表明，SLM算法和限幅类算法在性能上具有一定的互补性。任何一个算法未必能达到抑制PAPR的理
