ofdm通讯同步的经典SCA算法，通过测试程序无误，欢迎下载(ofdm communication synchronization classic SCA algorithm, through the test procedure correctly, please download the)

介绍了 Shannon 和 Huffman 编码的基本原理及 MATLAB实现方法，给出了编码实例,并进行了分析比较。 (Shannon Huffman coding is introduced and the basic principle and MATLAB methods, gives code examples, and are analyzed and compared.)

说明：  跳频通信中模式相加的原代码（配合Mmod.m，reMmod.m,U.m）一起使用。（附MATLAB库函数说明）(The sum of frequency-hopping mode of communication in the original code (with Mmod.m, reMmod.m, Um) use. (With MATLAB library function description))

说明：  本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行\\Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。 ( This directory includes: documentation and two source code. One of the source code is to identify the procedure, the other is a matrix class library, the book which is also used, so be attached. Because it has saved the trained network weights, so the first use of identification procedures, you can directly run \ \ Release directory of the executable files, and then tested on the images directory to read pictures, identification. Of course, readers are free to use the training samples to train the network, but pay special attention to training samples, otherwise it may cause very low recognition rate. Training sample selection principle is that as far as possible, representative, in the long training time Buzhi Yu s case, the number of training samples as much as possible. )

Kalman滤波开发包（matlab版）包括很多编得很好得函数，工具，功能非常强大，希望对研究得朋友有帮助(Kalman filtering Development Kit (Matlab version) including many of being good in function, tools, very powerful, and I hope to study in friends to help)

图像3D重建的源代码。是一个比较简单的example，大家可以学习。易于上手，图像重建的效果较好！(3D reconstruction of image)
