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.

PSK调制和解调，绘制星座图。有两个命令。分别是dmod和pskmod (PSK modulation Using matlab )

这是个卡尔曼滤波的递推程序，是用MATLAB实现的，很有用出的，希望对大家有所帮助(This is a recursive procedure of Calman filter is implemented in MATLAB, a useful, and they hope to help everyone)
