改进直扩系统数字匹配滤波SIMULINK建模(Improve the system of Direct Sequence Spread Spectrum Digital matched filtering SIMULINK modeling)

这是一个关于低密度检验码的很好的matlab程序(This is a low-density test on the code of good Matlab procedures)

SPWM产生器，带有谐波分析等功能，精度高，功能全(SPWM generator with harmonic analysis function, high accuracy, the functional)

内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

系统介绍了电子元器件失效机理和分析方法，图文并茂。很有指导意义(very good material introducing electro-component defect theory)

产生均匀分布的随机白噪信号,并观察数据分布的直方图(have a uniform distribution of random white noise signal, and observed data distribution histogram)

岩石受力破裂准则，莫尔圆模型，用于岩石受力下变形破裂分析。(rock mechanical ,moeryuan circle model)

time series In this example we will use a synthetic data set. To create our synthetic data we will make our unit of time 1000 years = 1 ky and sample a 500,000 year record in 2 ky increments. We first create a vector containing the times:
