Levenberg-Marquardt

An instrumentation system applied to formation flight

This is matlab model for ASK modulation techniques.

是指纹检测的matlab文件，解压后有一个TXT的文件说明可以，还包含几个图片，非常有用。(Is the fingerprint detection matlab file, after extracting a TXT document that can be, but also contains several pictures, very useful.)

《无线通信与原理应用》中QPSK编码的误码率曲线绘制的代码，简洁易懂。有注释，方便修改。("Wireless communications and Principle" in the QPSK coded BER curve drawing code, concise and easy to understand. Notes, easy to modify.)

利用Tikhonov正则化实现的超分辨率图像序列的重建，效果还好(Use Tikhonov regularization to achieve super-resolution image sequence reconstruction, better results)

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

均匀圆阵的指向性仿真和模拟，原创，最后求出其指向性图，参数可自行代换(Uniform circular array of directional and analog simulation, originality, and finally obtained its directivity diagram, parameters can be self-substitution)

Feature selection methods for machine learning algorithms such as SVR, including one filter-based method (CFS) and two wrapper-based methods (GA and PSO). The gridsearch is for the grid search for the optimal hyperparemeters of SVR. The SVM_CV is for the k-fold cross-validation of SVR. All the programs are flexible and could be implemented by the users themselves.

采用累计贡献率的方法，BP神经网络的整个训练过程,有信道编码，调制，信道估计等。( The method of cumulative contribution rate The entire training process BP neural network, Channel coding, modulation, channel estimation.)
