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

介绍了OFDM调制系统中的数字预失真技术及相关理论，但需要下载相应的知网阅读器才可阅读-a good paper about DPD in OFDM system,and CAJviewer is needed to read it
