摘要 主要围绕降低OFDM(正交频分复用)系统中峰均功率比(PAPR)展开研究。先对目前降低OFDM峰均功率比的各种技术进行了分析总结。然后,对信号畸变技术中的加权信号调制技术进行深入的研究和分析,通过仿真证明该技术可以有效地降低PAPR。本文所研究的内容均利用Matlab软件进行仿真。 This thesis mainly focuses on the techniques of PAPR reduction in OFDM （Orthogonal Frequency Division Multiplexing） system. Firstly, the researching achievement on reducing the PAPR are summarized. Secondly., weighted signal modulation technique in signal distortion techniques are analyzed. With simulation,the effect on PAPR reduction of this technique is testified. Finally,we give a summarize to this thesis, I also achieve the simulation of my research by Matlab.
