说明：  学习C调用Mathematica内核函数的一个例子,包括计算和图形接口.(Learning C calling Mathematica kernel functions with examples, including computing and graphics interfaces.)

基于小波变换的图像去噪的matlab程序的源代码，很好用！(based on wavelet transform image denoising the Matlab program's source code, easy to use!)

用两种递推最小二乘辨识的方法辨识吹风机函数。在加白噪声和有色噪声的情况下观察变化。两个辨识的结果与实际输出很接近，但是都会比实际的要大一点。有可能是对有色噪声的估计所引起的。噪声的增加不明显。(Identification by two recursive least squares method to identify a hair dryer functions. Observe the changes in the plus white noise and colored noise situations. Two identification results with actual output is very close, but it will be bigger than the actual. There may be an estimate of colored noise caused. Noise increase is not obvious.)

图像处理中通过小波实现图像增强。基于matlab函数实现。(Image processing wavelet image enhancement. Based on matlab function implementation.)

函数逼近,首先建立模型，使用径向基神经网络对被控对象进行逼近，希望都能到满意的效果(dasj sdij sdjosd asd )

Wigner-Ville分布相关程序及函数(Wigner-Ville distribution-related procedures and functions)

LDPC编译码仿真。部分迭代编码，不限定H矩阵类型，SPA算法译码。(LDPC codec algorithm in AWGN channel。)

基于CP的最大似然估计仿真图，两幅图，分别是符号定时偏差，以及频偏，从图中可以看出在符号定时估计最大处，相应的频偏估计值也是最接近的(CP-based maximum likelihood estimate simulation map, two maps, are a symbol timing offset, and frequency offset, it can be seen the figure in the symbol timing estimation is maximum, the corresponding value is also the closest frequency estimation)

说明：  DVBS2 system : transister + receiver
