This M Code simulate the effects of clipping and filtering on PAPR PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel is evaluated. The simplest and most widely used technique of PAPR reduction is to basically clip the part of signals that are outside the allowed region.Clipping methode introduces both in band distortion and out of band radiation into OFDM signals which degrades the performance including the BER and spectral efficiency.Filtering can reduce out of band radiation after clipping although it can not reduce in-band radiation distortion.However, clipping may cause some peak regrowth so that the signal after clipping and filtering will exceed the clipping level at some point.To reduce peak regrowth a repeated filtering and clipping operation can be used to obtain a desirable PAPR at a cost of computational complexity increase.

在用matlab做语音信号处理时经常用到的enframe等函数，这在matlab中是没有的，需要下载专门的工具箱，这是从官网上下载的，可直接解压安装。具体安装方法网上一搜就能搜到。(Frequently used in speech signal processing using matlab enframe function in matlab there is no need to download a special toolbox, which is downloadable from the official website, you can directly extract the installation. Specific installation methods online search can be found to)
