说明：  中间的程序是外推程序,......... 但是下面的程序仿真部分和外推部分的标号有写出入,因为不是同一时期编的 请大家注意： 程序中用的是频域外推法，在葛德彪的书中有详细的介绍。(Central procedure is the extrapolation procedure ,......... but some of the following procedures for simulation and extrapolation part of the labeling has to write out, because they are not made during the same period the U.S. Please Note: The procedure used is the frequency of extra-territorial extrapolation method, in the GE De-biao book has a detailed introduction.)

this is the matlab code for dip lab programs

(2,1,3)卷积码编码，硬判决译码；编码是matlab语言，译码是verilog语言((2,1,3) convolutional code encoding, hard decision decoding coding is matlab language, decoding is verilog language)

对图像加入白噪声干扰，用维特比译码进行去扰，分别用硬判决和软判决，显示出的图像可以看出不同的效果(White noise is added to the image, performed using Viterbi decoding descrambling, respectively, with the hard decision and soft decision, showing the different effects can be seen in the image)

模拟退火算法，经过调试可以运行，效果不错(simulated annealing algorithm which has been tested with good performance)

利用MATLAB实现相机的几何标定，求取对应的摄像机外参和内参(Using MATLAB to realize the geometry of the camera calibration, calculate the corresponding cameras outside and inside)

纹理图像分割论文和代码，还算比较完整的，对做方面毕业设计的有点用！(Texture image segmentation papers and code are fairly more complete, to make the design a bit to use in graduate!)

说明：  matlab中文帮助，非常有用哦！！！！(matlab Chinese help, very useful oh! ! ! !)

一种智能优化算法-人工神经网络算法的matlab源程序(artificial neural network)

MATLAB是一套功能十分强大的工程计算及数据分析软件,具有友好的可视化编程界面及接近数学表达式的自然化语言。针对信号与系统中傅里叶变换具有抽象度高、难于理解的特点，利用MATLAB强大的信号处理功能、阶跃响应，微分方程，卷积定理的内容，通过MATLAB 程序实现。本文介绍了MATLAB在信号与系统仿真中的应用,该软件在通信电子类课程中应用越来越广泛,通过几个典型实例来重点研究。 关键词：MATLAB；阶跃响应；微分方程；卷积；信号与系统；仿真 (MATLAB is a very powerful engineering calculations and data analysis software, with a friendly interface and visual programming language close to naturalizing mathematical expressions. For the Fourier transform of signals and systems with a high degree of abstraction, it is difficult to understand the characteristics, the use of the powerful MATLAB signal processing functions, step response, convolution theorem content differential equations by MATLAB program. This article describes the application of MATLAB in signal and system simulation, the software in the electronic communications courses in applied more widely, by focusing on a few typical examples. Keywords: MATLAB step response signals and systems convolution differential equation simulation )
