说明：  matlab或c++语言，有关最小二乘编程问题(math and matlab)

通过比较奇异谱图和高阶奇异谱图得出结论：高阶奇异谱分析能够更好的二次确定嵌入维数。最后根据Takens嵌入定理进行相空间的重构。(By comparing the spectra of singular spectrum and higher-order singular conclusion: High singular spectrum analysis to better determine the embedding dimension of the secondary. Finally, according to Takens embedding theorem for phase space reconstruction.)

采用高斯平滑滤波，多种算子进行边缘检测，设定阈值，两种算法进行图像分割(Gaussian smoothing filter, a variety of edge detection operator, set threshold, the two algorithms for image segmentation)

6-Application of Nonlinear PID Controller in Superconducting

《雷达系统设计MATLAB仿真》一书附带的所有程序和函数，包括信号仿真以及模糊函数的实现(The radar system design matlab simulation, a book comes with all procedures and functions, including signal simulation and Realization of the fuzzy function)

OFDM仿真代码，对理论值与实际值做了相应对比。 (OFDM simulation code, to the theoretical value to do with the actual value of the corresponding contrast.)

说明：  在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)
