precoding

说明：  用MATlab神经网络来做预测的例子，有用的人可以下来看看(Neural network to do prediction with MATlab example, useful to see who can down)

本程序是快速独立成分分析算法中需要调用的一个很重的子程序。(This procedure is fast independent component analysis algorithms need to call a heavy subroutine.)

fisher变换可以将 维空间的样本投影到一条直线上，形成一维空间，这个就是用matlab解决fisher的例题(the fisher transform a sample-dimensional space can be projected onto a straight line, forming a one-dimensional space, this is solved with matlab fisher Example)

以前西电研究生DSP大作业代码，都是C语言和Matlab完整版，可以供大家编程参考 (Former Western Electric graduate DSP great job code, C language and Matlab full version, can be programmed for your reference)

用于提取sift特征，准确地说是提取dsift 特征，即密集采样的sift特征(it is used to extract dsift feature ,sdfasdfjlkajsdlkfjlkasjdf)

在matlab中，用小波实现语音去噪。噪声为正态随机噪声(In matlab, the Speech Denoising by Wavelet. Noise for the normal random noise)

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)
