matlab 语音混沌加密（logistic映射）带本机传输

武汉理工大学《数字信号处理》精品课件！获国家精品课程展示！有刘泉教授主编！(Wuhan University of Technology, " Digital Signal Processing" fine courseware! Won the national Quality Course show! There Professor Liu Quan editor!)

说明：  编写一个程序，对输入的图像进行哈夫曼编码，显示原图像的熵、编码后的平均码字长度、并能够根据编码重建出图像。 Sobel算子和拉普拉斯算子进行锐化，并比较结果。(Write a program to image the input Huffman coding, the entropy of the original image displayed, encoded, the average code length, and be able to reconstruct the image according to encoding. Sobel operator and Laplacian sharpening, and compare the results.)

本文件用matlab 语言，对kalman滤波的方法进行仿真，画出来原始曲线，观察值，和跟踪曲线，会对初学者有很大的帮助！(this document using Matlab language, Kalman filtering method simulation, sketching out the original curve, observed values, and tracking curve, beginners will be of great help!)

one dimensional PCF band simulation(one dimensional simulation PCF band)

时域处理算法，本源码是关于时域预处理放面的内容，包含简易的算法(Time domain processing algorithms, the source is placed on the surface pretreatment time-domain content, including a simple algorithm)

该程序用一个实例进行演示线性回归方程的建立。(The procedures used to establish an instance demonstrates the linear regression equation.)

用于学习经典书籍《合成孔径雷达算法与实现》(to learn the book named<<digital processing of SAR Algorithms and implementation>>)

MATLAB非线性混沌工具箱：时间延迟、嵌入维、最大李雅指数级关联维、熵等参数。有了自己就不用编程了！(The MATLAB nonlinear chaotic toolbox: the time delay, embedding dimension, maximum Josephine exponential correlation dimension, entropy and other parameters. With their own without programming!)

基于折反射定律和衍射理论，利用蒙特卡罗方法，建立了阵列微透镜的蒙特卡罗数值模型，并利用高斯光束通过阵列微透镜聚焦对程序进行验证能够准确模拟光子通过微透镜传输时的光路。
