说明：  南航写的gps仿真器源码，用matalb编写的一个比较简单的GPS仿真器，供大家学习和参考。(China Southern gps emulator written source, matalb prepared using a relatively simple GPS simulator for them to learn from and reference.)

系统辩识在matlab里的应用:输入信号的产生,多种最小二乘的辨识(system identification in the application of Matlab Lane : input signal the emergence of a variety of literacy least squares)

DCT域的数字水印的嵌入和提取算法，针对的载入原始图像和水印图像都是二值图像(DCT digital watermarking embedding and extraction algorithm for the load are the binary image of the original image and the watermark image)

直接序列扩频通信系统误码率分析,主要过程为基带信号生成，扩频，解扩，误码率分析(Direct sequence spread spectrum communication system BER analysis, the main process for the baseband signal generation, spreading, despreading, BER analysis)

Matlab可视化界面设计与控件使用源代码名称：exam 调试环境：Win XP；Matlab 6.5 (Matlab visualization interface design and control the use of the name of the source code: exam debugging environment: Win XP Matlab 6.5)

粒子群优化源程序 本人已通过matlab实现 希望对大家有用(Particle swarm optimization matlab source code I have passed to achieve the desired useful to everyone)

一本很好的matlab学习书籍，综合了很多的内容，英文版的，对英文又要求( Matlab learning good book, synthesized a lot of content, the English )

里面有两组数据，然后分为训练样本组和测试样本组，都采用fisher准则判定，再对结果惊醒分析(There are two sets of data, and then divided into groups of training samples and test samples group, have adopted guidelines for determining fisher, and then woke up on the results of the analysis)

The architecture of this set of codes and the interaction among them is shown in Figure 1. The main testing code main code.m calls the code riemann grad unit opt.m that performs Riemannian optimization under unitary matrix constraint. Steepest Descent/Ascent (SD/SA) algorithm (see Table 3.2 in [1]), Conjugate Gradient (CG-PR, CG-FR) algo- rithms (both Fletcher-Reeves and Polak-Ribi`ere formulas, see Table 3.3 in [1]), are im- plemented. This code further calls the codes implementing line search methods: Armijo method geod search armijo.m, as well as the polynomial and DFT-based approximation

this is coding of dwt in matlab
