使用log-map sova 进行turbo 并有完整(use log-map sova decode the turbo code)

说明：  MATLAB编写的求最值的小程序，效果很好，同时很有应用价值啊(MATLAB prepared the most value for small procedures, the effect of a very good value at the same time very ah)

作者在学习《航天系统》时，在c++6.0环境中实现的卫星定位的算法程序。包括通过轨道根数求卫星状态参数的算法和通过卫星状态参数反求卫星星历的算法。(Author of the study "space system" is in c++6.0 environment to achieve the satellite positioning algorithm. Including through the orbital parameters of the algorithm for the satellite status and Reverse status parameters via satellite satellite ephemeris algorithms.)

利用matlab软件来绘制Chessboard，可以用于摄像机张正友方法的标定(Using matlab software to draw the Chessboard, the camera can be used to calibrate the method of Zhang Zhengyou)

程序1实现了一维Airybeam的三维图形，从x-y面可以看出Airybeam的传输轨迹，三维图形的z轴是光强； 程序2实现了1维Airybeam的轨迹控制，通过改变wm和wg的值可使光强的最大值在任意位置。(A three-dimensional graphics program to achieve a one-dimensional Airybeam the xy plane can be seen Airybeam transfer trajectory, and three-dimensional graphics z-axis is the light intensity 2 implements the program track 1-dimensional Airybeam control, by changing the value of wg wm and the light intensity at an arbitrary position allows the maximum.)

relay selection and path loss function to max the snr

用MATLAB运行主成分，可以求出特征向量，等非常实用。(MATLAB operation principal component, can work out characteristic vector, and very practical. )

基于matlab软件实现等距离离散化为粗糙集约简前准备(matlab Equidistance discretization)

用matlab实现的曼彻斯特 NleyPu编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的DwxXJnF 的通信原理课件上的形状一模一样。 .(With Manchester NleyPu encoding matlab realize. 50 duty cycle (adjustable) . Draw time-domain waveform and frequency domain power spectral density. Results with BUPTDwxXJnF Exactly the same shape Wenbin communication on the principles of courseware.)

说明：  EMD matlab实现代码，可以直接用。经验模态分解（Empirical Mode Decomposition，EMD）是由 Huang等人于1998年提出的一种针对非线性、非平稳信号的自适应信号分解算法。(Empirical Mode Decomposition (EMD) is an adaptive signal decomposition algorithm for non-linear and non-stationary signals proposed by Huang et al. in 1998.)
