This is a work-in-progress. Please check back for updates, and check software carefully before using!

说明：  使用matlab画的smith圆图，但是没有动态的显示。(Smith painting using matlab circle diagram, but no dynamic display.)

这是一个利用BP神经网络进行分类学习的程序，系统输入为4个，输出为1个(This is an advantage of BP neural network to classify the learning process, the system input is 4, the output is a)

信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )

光网可靠性分析，matlab实现。。自我修复功能，分析光网网络可靠性的算法(Optical network reliability analysis, matlab realize. . Self-healing capabilities, network reliability analysis algorithms optical network)

改进的平方根法，可以被调用，已知数组需自行设定(Improved the square root method can be called, known array to be set)

eemd,emd 分解相关降噪相关包括自相关原理等(eemd, emd decomposition related noise and other relevant principles include autocorrelation)

说明：  计算时变重力场变化的程序，通过此程序可以计算地球质量变化等等。(Changes in time-varying gravity field calculation program, this program can be calculated by changes in Earth' s mass and so on.)

计算峰值信噪比和信噪比的小程序。分享给大家。(PSNR and SNR calculation applets. For everyone to share.)
