一篇关于GPS和北斗2代原理的文章，写的非常详细，堪称经典。(GPS and Compass article on behalf of the principle of article 2, write a very detailed and classic.)

GMSK和MSK调制解调系统的眼图，误码率图，很好(GMSK and MSK modulation and demodulation system eye diagram, bit error rate figure, very good)

说明：  对原始信号进行EMD分解及包络解调，得出包络解调谱，分析出故障频率(The original signal is decomposed by EMD and demodulated by envelope. The spectrum of envelope demodulation is obtained and the fault frequency is analyzed.)

这是国外关于卫星导航方面一书的源代码，相信对初学者会有很大的帮助，里面包含位置计算、星历计算、模糊度计算等功能。(This is the foreign aspects of satellite navigation on the book s source code, I believe there will be a great help for beginners, which contains the location of computing, ephemeris calculation, calculation of ambiguity functions.)

连续像对相对定向元素计算-摄影测量学必备(And continuous relative orientation- Photogrammetry)

这个是盲均衡算法的matlab仿真功能代码，分析了接收机信号经盲均衡算法后，有效提升接收机性能，具有一定的参考价值(This is a blind equalization algorithm matlab simulation function code, analysis of the receiver signal by the blind equalization algorithm, effectively improve the receiver performance, with a certain reference value)

一维配点型无网格法的MATLAB编程源代码(MATLAB programing code of 1D collocation meshless method)

说明：  超好的GPS信号仿真软件，本人研究生期间编写，可以作为深组合导航的数据源(Good GPS signal simulation software, compiled during my graduate school, can be used as the data source of deep integrated navigation)

16QAM调制的OFDM，在限幅作用下输入输出互信息的变化情况(Mutual information of 16QAM modulated OFDM, with various clipping )

说明：  对加入水印的图像进行检测，水印加入算法是上一个上传的程序 add_score.m(to join the watermark image detection, joined the watermark algorithm is a procedure upload add_score.m)
