fft，本代码主要介绍fft的主要步骤，非常简单有很明了，非常适合阅读 (FFT, the code describes the main steps of FFT are very clear, very simple, very suitable for reading)

改进的CMA，便于载波恢复。这是一个非常好的算法，精心编码(a modified CMA used for phaes recovery)

说明：  自制的快速傅立叶变换函数，可以用来对比工具自带的fft函数，比较其执行时间随Ｎ值变化的情况(privately fast Fourier transform function can be used to contrast the instruments onboard fft function, compared with the time of its implementation N changes in the value of)

一些干涉仪算法的代码，包括music算法，DOA估计，干涉仪测方位角(Code for some interferometer algorithm，such as MUSIC algorithm, DOA estimate)

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.

高阶谱分析工具箱 matlab版的 很好用的 希望对大家有帮助(higher order spectral analysis Matlab Toolbox version of the good wishes to be helpful)
