PID调节器结构简单、参数易于调整，当被控对象精确数学模型难以建立、系统的参数又经常发生变化时，应用PID控制技术，在线整定最为方便。 (PID adjustor simple structure, easy adjustable parameters, when the controlled object mathematical model is hard to build up, the parameters of the system and often changes, application of PID control technology, online setting the most convenient.)

跳频（占空比为0.1）4fsk的部分频带干扰误码率计算，这个程序是基于matlab的，自己编的，呵呵(Frequency Hopping (duty cycle 0.1) 4fsk the partial band interference bit error rate, this procedure is based on matlab, and their series, Oh)

”BP.m“文件是BP神经网络整个模型的源程序； “train.fig”是训练时最后得到的图片； “程序运行的人口数量原始数据.fig”是预测结果绘制的图； “程序运行时matlab命令窗口的内容.txt”是运行程序是在matlab命令窗口显示的东西； “程序运行完产生的数据.mat”是程序运行完毕产生的数据。 .bmp文件和.fig文件一样()

说明：  PWM整流器仿真，稳压效果好，采用svpwm调整，pll锁相环并网，电流波形纹波小，响应快(Simulation of PWM rectifier shows that the effect of voltage stabilization is good, SVPWM adjustment is adopted, PLL phase-locked loop is connected to the grid, the current waveform ripple is small and the response is fast)

这个是burger方程，李群的方法，求生成元(This is a burger equations, Lie group methods, and generator)

说明：  通信系统的模拟仿真程序，可以根据需要建立自己的仿真模型(communications system simulation process can be required to establish their own simulation model)
