Symbolic Representations of Time Series... SAX is just as good as other representations, or working on the raw data for most problems (Slides shown at the end of this presentation)

给一个受污染的声音文件用滤波器用matlab消除噪声(Give a contaminated audio files using filter to remove noise)

2fsk的调制及加入高斯白噪声后相干解调误码性能(Modulation 2fsk and by adding white Gaussian noise and coherent demodulation error performance)

基于matlab的图形图象加密算法，对图形图象进行行列变换，达到对图象进行加密的功能。(Matlab-based graphical image encryption algorithm, to transform the ranks of graphics images to be encrypted on the image function.)

这是本人编写的PLS建模程序，希望对大家关于该方面的研究有帮助。(This is my procedure to prepare the PLS modeling, I hope all of you on the research helpful.)

DES3200实验系统的模拟信号输出通道产生一个1KHz 的方波,然后利用信号输入通道对产生的方进行低通滤波,得到一个1KHz 的正弦信号，并使用CCS 的图形显示工具显示输入和输出的波形。这里我们使用的是一个46阶的对称结构的FIR低通滤波器，其采样频率Fs为25KHZ，通带截止频率 1KHZ，阻带截止频率为3KHZ，阻带衰减为-60dB。(DES3200 experimental system analog output channel generates a 1KHz square wave, and then use the signal input channels that produce low-pass filtering the square to get a 1KHz sinusoidal signal, and use the CCS' s graphical display tool shows the input and output waveforms. Here we use a symmetrical structure of 46-order FIR low-pass filter, the sampling frequency Fs to 25KHZ, passband cutoff frequency 1KHZ, stopband cutoff frequency 3KHZ, stop-band attenuation is-60dB.)
