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.

The progress of the research in wireless communications and in other areas stimulates the rapid development of WSN. The motivation for the development of WSN is their flexibility, relative ease of installation (e.g., in places with radioactive pollution), lower power consumption etc. As can be concluded from [2], a WSN - is an infrastructure comprised of sensing, computing, and wireless communication elements that provides the ability to instrument, observe, and react to events and phenomena in a certain environment. The information obtained by sensors can be used for civil, governmental, commercial, or industrial purposes.
