基非下采样的Contourlet变换的图像融合，要放到NSCT工具包中执行(Under the base of non-sampling Contourlet transform image fusion, to put the implementation of the toolkit NSCT)

Probability of error 8 PAM

对2维doa进行估计，在不同的快拍数情况下，BPSK信号的经典MUSIC估计比单频信号的经典MUSIC估计方法均方根误差性能更好(On 2 d to estimate doa. In different fast take several cases, BPSK signal of classical MUSIC estimate than single frequency signal of the classical MUSIC estimation method root mean square error performance better. )

Audio Stegnography by using LSB Agorithms...

Very often I see people asking for a tool that offers more than 16 digits or so of accuracy. MATLAB itself only allows you to use doubles or singles in standard arithmetic, so that is the normal limit. The fact is, most of the time, if you can t do it with a double, you are doing something wrong. Good practices of numerical analysis are worth far more than any high precision tool. Even so, there are times when you will have a use for a bit of extra precision. And some of you will just want to play in the huge number sandbox. While some of you may use tools like that written by Ben Barrowes, HPF is written purely in MATLAB, so no compiles are needed. For all of you, whatever your reasons, I offer HPF, a High Precision Floating point tool.

小波去噪程序 在噪声环境下语音信号的增强 语音信号为读入的声音文件 噪声为正态随机噪声 (Wavelet denoising process voice signals in a noisy environment, the enhanced speech signal into a sound file for read noise is normal random noise)

这个程序可以很方便实现最佳匹配问题，操作比较简单，容易看懂(This procedure can be very convenient to achieve the optimal matching problem, the operation is relatively simple, easy to understand)

kalman的学习资料 很好的东西 一起学习吧(kalman learning materials to learn something good with it)

说明：  通带截止频率 =2 4k rad/s，阻带截止频率 =2 8k rad/s，通带波纹系数 =0.3dB, 阻带波纹系数 =50dB,采样频率fs=20000Hz。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter.)

算法由于提供了一个预测值,相对来说有简化.第五种方法,也就是ode45所得的精度最高尺度到了1e-18...简直可怕!一般很少有工程问题是它不能够满足的了,能够看出,解的差别在本问题里已经很明显了. (algorithm providing a predictive value, a relatively simplified. Fifth, ode45 is the highest accuracy of a scale of e-18 ... is simply terrible! it seldom works that asked that is not able to meet it in the can see that the solution of differences in the issues it is already very clear.)
