GPS信号存在转发式欺骗干扰时，做出欺骗信号和真实卫星信号的相关峰图，其中伪码生成采用weil码(The presence of repeater jamming GPS signals to make the correlation peak to deceive the true signal and satellite signal, wherein the pseudo-code code generation using weil)

ti 的Tms320F28xx的在线仿真内核.gel文件！(ti' s Tms320F28xx online simulation kernel. gel file!)

介绍了三点垂直线阵被动定位的原理. 结合矢量水听器测得的方位角和高低角及到达 阵元间的时延差, 建立了三维坐标下的状态方程和观测方程.运用扩展卡尔曼滤波算法, 研究了该系统的目标运动分析问题. 通过蒙特卡洛模拟仿真试验, 结果表明上述方法具有较高的定位性能,有较强的使用价值. (Introduced three vertical linear array passive location principle of vector hydrophone. Combining the measured azimuth angle and pitch angle and arrival time delay difference between array elements, establish the three-dimensional coordinates of the state equation and observation equation. Using the extended Calman filter algorithm, on the target motion analysis by Monte Carlo simulation. Test, results show that the method has high positioning performance, has the strong use value.)

非常经典的数字信号处理书籍，清华大学程佩清的(Very classic books digital signal processing, Tsinghua University cheng pei qing )

西安交大数字信号处理课程PPT，研究生教程，需要的同学可以学习一下(Xi an Jiaotong University, Digital Signal Processing PPT, graduate tutorials, needy students can learn)

GPS信号的捕获、处理程序，matlab源代码，并附有详细注释，和结果画图显示。强烈建议GPS学习者下载。(GPS software receiver。)

说明：  遗传算法优化极限学习机的权值和阈值，以提高辨识能力(Genetic algorithm optimizes the weight and threshold of the extreme learning machine to improve the identification ability)

这个程序采用现代谱估计的ARMA参数模型算法对信号的功率谱做了估计(The program uses the ARMA parameter model algorithm of modern spectral estimation to estimate the power spectrum of the signal.)

说明：  谢菲尔德大学的MATLAB遗传算法工具箱，已经试过，很好用，在这里分享给大家。完全解压后将文件放到matlab的toolboxs里，再打开matlab的set path添加保存(The MATLAB Genetic Algorithm Toolbox at the University of Sheffield has been tried and used very well and is shared here. After fully decompressing, put the file into the toolbox of matlab, and then open the set path of matlab to save it.)

可以得到很精确的幅值、频率、相位估计，基于K均值的PSO聚类算法,光纤陀螺输出误差的allan方差分析。( You can get a very accurate amplitude, frequency, phase estimation, K-means clustering algorithm based on the PSO, allan FOG output error variance analysis.)
