中文说明：多抽样率信号处理，采用的是通用的平面波展开法,关于非线性离散系统辨识，采用的是脉冲对消法，计算晶粒的生长，入门级别程序,仿真效果非常好。
English Description：
Multirate signal processing using the common plane-wave expansion method, nonlinear discrete-time system identification, using a pulse cancellation method, calculation of grain growth and entry level program, and its effect is very good.
