离散频谱比值校正法 hamming hanning(The ratio of discrete spectrum correction method hamming hanning )

基于短时傅里叶变换的对鼾声信号进行分析，可以计算一些判断OSAHS的指标。(snoring analysis based on STFT)

ofdm系统的简单仿真，基于matlab环境，可以借此更好的理解ofdm传输原理(simple simulation ofdm systems, based on the matlab environment, can take a better understanding of the principle of ofdm transmission)

巴特沃斯低通，巴特沃斯高通滤波器。matlab实现，用于图像平滑处理，去噪。(butworth，filter。)

说明：  这是一个工具，使用MATLAB代码为一个由阿尔伯塔大学的Siting Liu开发的硬件Sobol序列生成器生成VHDL文件。(This is a tool that uses MATLAB code to generate VHDL files for a hardware Sobol sequence generator developed by Siting Liu at the University of Alberta.)

自编的快速傅里叶变换的matlab程序，已经经过调试了，是可用的(Self matlab program fast Fourier transform, has been debugged, it is available)

Low pass and High Pass filters aplied to images as sobel, prewitt, roberts, first derivative

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

说明：  本文件可以用来精确计算M-K趋势值，以及倾斜度。 matlab的m文件 直接点击F5运行(This file can be used to accurately calculate the the MK trend values, as well as the inclination. matlab m file directly Click F5 to run)

说明：  EMD算法的matlab代码，非常详细，每一步都有解释(Matlab code of EMD algorithm)
