摘　　要：首先介绍了优化初相抑制多载波信号波峰因子的方法和效果;其次对削波抑制波峰因子进行了分析和仿真,对比了直接削波和窗函数削波对信号波峰因子的抑制结果和对信号频谱杂散的影响;然后仿真分析了高斯窗函数中参数变化对削波效果的影响;最后给出了窗函数削波的FPGA实现架构。This paper firsdy introduce the method and effect on crest factor reduction of multi-carrier signal by optimizing initial phase. Secondly analyze and simulate crest factor reduction by clipping. Especially contrast the crest factor and spur of signal between direct clipping and Gaussian window clipping. And simulate the different effects of clipping by the change of Gaussian window＇s parameters. Lastly give the realizing frame of FPGA based on window clipping.
