说明：  语音增强的谱减法算法实现，要有一个wav格式的声音文件(Spectral subtraction speech enhancement algorithm, there must be a wav sound file format)

基于NSCT和PCNN的图像融合算法，提高了融合效果。(base on nsct-pcnn page_fusion)

基于Huang TS提出的快速中值滤波算法的MATLAB程序(Based on Huang TS a fast median filtering algorithm MATLAB program)

偏最小二乘法是一种数学优化技术，它通过最小化误差的平方和找到一组数据的最佳函数匹配。 用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。(Partial least squares method is a kind of mathematical optimization technique, it through the minimum error sum of squares to find a set of data the best function matching. With the Jane s method for some absolutely unknowable true value, and make the sum of error square to a minimum.)

实现了卷积码（2,1,3）编码以及解码的功能，已验证通过(Achieved (2,1,3) convolutional encoding and decoding functionality code validated by)

LMS算法是一种很有用且很简单的估计梯度的方法。这种算法60年代初得出以后很快得到应用，它的突出优点是计算量小易于实现，且不要求脱线计算。只要自适应线性组合器每交迭代运算时都知道输入信号台和参考响应，那么，选用LMS算法是很合适的。(LMS algorithm is a very useful and very simple estimate of the gradient method. The algorithm reached 60 soon after the early applied, it is to calculate the amount of the outstanding advantages of a small easy to implement, and does not require off-line calculation. As long as the adaptive linear combiner time per each iteration all know that Taiwan and the reference input signal response, then the selection of LMS algorithm is very appropriate.)

使用MATLAB打开TXT文件，并且用文件里面的数据画图(Open the TXT file using MATLAB, and use the data inside the drawing file)

脉冲编码调制是数字通信的编码方式之一。主要过程是将话音、图像等模拟信号每隔一定时间进行取样，使其离散化，同时将抽样值按分层单位四舍五入取整量化，同时将抽样值按一组二进制码来表示抽样脉冲的幅值。(PCM pulse code modulation is one of the encoding methods of digital communication. The main process is to voice, image and other analog signal at a certain time for sampling, the discretization, while the sampling values by the hierarchical units four to five homes in rounding quantization, while the sampling value indicates the sample pulse amplitude according to a set of binary code.)
