OFDM降低峰平比采用预失真技术，程序仿真了加入预失真技术后的星座图与未加预失真的比较。结果比较明显。采用QAM映射。-OFDM PAPR reducing the use of pre-distortion technology, process simulation technology to join the pre-distortion of the constellation diagram and the following not pre-distortion comparison

用QAM调制的ofdm信号，利用SLM方法降低峰均功率比，可与QPSK方法调制的信号比较学习-With QAM modulation ofdm signal, the use of SLM to reduce the PAPR, with QPSK modulation signal comparison method to study
