Description: 在许多的数据采集系统中，现场的强电设备较多，不可避免
地会产生尖脉冲干扰,这种干扰一般持续时间短，峰值大，对这样
的数据进行数字滤波处理时，仅仅采用算术平均或移动平均滤波
时，尽管对脉冲干扰进行了1/n的处理，但，其剩余值仍然较大。
这种场合最好的策略是：将被认为是受干扰的信号数据去掉，这
就是防脉冲干扰平均值滤波法的原理。-In many data acquisition system, the strong electrical equipment at the scene more, will inevitably produce a sharp pulse interference, such interference generally short duration, peak, and data on such digital filter processing, only the use of arithmetic mean or moving average filter, although carried out on the pulse interference 1/n the treatment, but its residual value is still larger. Such occasions, the best strategy is: would be considered interference signal data removed, and that is anti-pulse interference principle average filtering method.

Description: This M Code simulate the effects of clipping and filtering on 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.
