Frequency Modulation

稀疏表示分类算法在ORL人脸库上的实验，参考文章： Wright J, Yang A Y, Ganesh A, et al. Robust face recognition via sparse representation[J]. Pattern Analysis and Machine Intelligence, IEEE Transactions on, 2009, 31(2): 210-227. (Sparse representation classification algorithms on ORL face experiments, refer to the article: Wright J, Yang AY, Ganesh A, et al Robust face recognition via sparse representation [J] Pattern Analysis and Machine Intelligence, IEEE Transactions on, 2009, 31 (2):.. 210-227.)

matlab 本身没有箭头功能，只有梯度，梯度不能精确，这是编写的箭头功能，可以精确定位箭头三维位置(matlab function itself has no arrows, only gradient, the gradient is not accurate, it is written in the arrow function, you can pinpoint the location of the arrow D)

说明：  matlab 实现文字提取 及正负面分析(Text Classication and Sentimental Analysis)

说明：  是关于通信仿真的几个程序，里面有调幅、调频等的仿真程序代码！(Communications simulation on several procedures, which has AM, FM, such as the simulation program code!)

说明：  fft算法，fft与dft算法的比较，并有详细的文档说明。(fft algorithm, fft compared with the dft algorithm and a detailed description of the document.)

一个KKV标准弹道仿真程序，仿真了KKV在中段拦截TBM的弹道。供大家参考。下面还会上传其他方法仿真的程序。(KKV standard ballistic simulation program, the simulation of KKV in the middle of the TBM interception trajectory.For your reference.The following simulation program also upload other methods.)

利用mathlab仿真雷达脉冲压缩测距原理。对两个雷达回波信号进行脉冲压缩实现可分辨。(Using mathlab simulation principle of pulse compression radar ranging. The two implementing pulse compression radar echo signals can distinguish. )

双基地声呐定位精度GDOP的分布图，以及与单站方位估计误差的关系。(Bistatic sonar maps GDOP positioning accuracy, as well as the relationship between the error of estimation and single station azimuth.)
