Coding and decofing using turbo codes

使用matlab编写的经纬高、东北天数据和地心坐标数据之间的转换函数文件，包含了东北天坐标系的定义说明文件以及相关的转换公式。 三个函数的调用文件名：ECEFtoENV，ECEFtoLBH，LBHtoECEF。使用说明见函数的说明。(Prepared using matlab high latitude and longitude, northeast-day data and geocentric coordinate conversion functions between data file that contains the definition of the coordinate system Northeast day documentation and related conversion formulas. Three function calls filename: ECEFtoENV, ECEFtoLBH, LBHtoECEF. See the instructions for use function.)

Compression DICOM images using different method according to region of interest (ROI)

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding the SNR to see how well decompression works

三机九节点simulink仿真电路图包含详细的参数和模型(Three machines nine simulink simulation circuit node contains detailed parameters and models)

说明：  解决matlab 7.0 simulink不能保存的问题，将本文件放在work目录下，重启matlab即可(Solve matlab 7.0 simulink can not save the problem, work on this document directory, you can restart matlab)

很好很实用的matlab工具函数包括：插值与拟合等相关问题的实现(Nice and useful tool matlab functions include: interpolation and fitting, and other related issues to achieve)

说明：  MATLAB高级编程,MATLAB工程数学,MATLAB实用教程,MATLAB图形图像等源码集锦(MATLAB high-level programming, engineering MATLAB mathematics, MATLAB practical guides, such as MATLAB graphics source Collection)

这个程序对于学习流行学习算法的朋友很有借鉴意义，在matlab上能够运行。(This program for the popular learning algorithm friends is of great significance, to be able to run in matlab. )

关于viterbi编码的，与信道编码有关，很适用(viterbi_decoder3_p)
