pts_paprofdm.rar - pARTIAL TRANSMIT SEQUENCE is very effective technique for papr reduction in OFDM.It divide OFDM sequence into several disjoint sub sequences and convert to time domain then
Combine with complex phase factors to reduce PAPR.In this code matlab simulation of this technique is implemented
PAPR-Reduction2.rar - 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.
PTSandClippingtoReducePAPR.rar - 使用PTS和限幅联合算法降低OFDM峰均比.提出了一种降低正交频分复用(OFDM)系统峰均比(PAPR)的联合算法:部分传输序列(PTS)和限幅(Clipping)算法.该联合算法先利用PTS算法对OFDM信号进行处理以降低PAPR,所得信号再利用限幅法进行处理,以进一步降低PAPR.
OFDM.rar - clip&Filter,PTS和SLM三种降低PAPR的方法以及其优化算法，代码简单，注释丰富，绝对可以运行，有很大的参考价值。
