混合扩频DS/FH仿真程序，从原始信号通过伪随机码，跳频码转变为混合扩频信号，再依次解跳解扩，最后通过低通滤波器恢复出信号。(Hybrid spread spectrum DS/FH simulation program, from the original signal by pseudo random code, frequency hopping code into a hybrid spread spectrum signal, and then hopping despreading, finally through a low-pass filter to recover the signal.)

说明：  用遗传算法进行多元函数的优化，是测试函数与数据集的基本方法(Using genetic algorithm to optimize multivariate function is the basic method of testing function and data set)

DES的MATLAB文件。。。有很好的操作界面(use matlab to achieve des)

说明：  这个仿真程序可以仿真牛头刨床的运动形式，解牛头刨床的运动加速度等。(This simulation program can simulate the form of the movement of the planer, the solution of the movement of the planer acceleration.)

步进电机失步情况的一个仿真.这是一个比较完整的方针,但是仅仅考虑了在单个脉冲下的失步情况.(Stepper motor out-of-step situation in a simulation. This is a relatively comprehensive approach, but considered only in a single pulse under the out-of-step situation.)
