基于脉冲整形的PAPR抑制matlab源代码(matlab source code for reducing PAPR of OFDM signal with PS methed)

快速傅立叶变换的matlab实现，一维情况下利用蝶形算法实现(Fast Fourier Transform Implementation of Matlab, a dimension of the use of butterfly Algorithm)

此程序主要功能是 1 画出标准零阶贝塞尔函数， 2 在估计多普勒时，接收信号的实部或者虚部的自相关函数接近于贝塞尔函数，所以画出了一条接近于贝塞尔函数的曲线图(The main function of this program is 1 shows the standard zero-order Bessel function, 2 estimate the Doppler, the autocorrelation function of the received signal or the imaginary portion of the real part close to the Bessel function, so to draw a graph of the Bessel function is close to)

灰色预测程序，由于少数据量的预测比较准确(Grey forecasting process is a more accurate forecast, due to a small amount of data)

地震信号处理当中应用小波去除面波干扰，小波变换后进行阈值处理，反变换之后得到面波压制后的地震信号(Surface wave seismic signals obtained after the seismic signal processing to suppress them after removing the surface wave interference wavelet, wavelet transform thresholding, anti transformed)

鱼眼校正用matlab编写，可以得到矫正后的图片(Radial distortion)

说明：  可以用这份代码做粒子滤波，效果还行，这个是无迹的算法(This code can be used for particle filtering.)

模极大值滤波，对信号进行分解和重构。所采用信号是matlab自带信号。(Modulus maxima filtering, the signal decomposition and reconstruction. Signal is used in signal matlab own.)
