这是基于邻域粒化和粗糙逼近的数值属性约简matlab代码(This is a neighborhood-based grain and rough approximation of the value of attribute reduction matlab code)

that the performance is improved by increasing N, and probability of detection can be improved by increasing N value even if the SNR is much lower, as long as N is large enough without noise uncertainty.

本代码包括小波包能量的提取，可以用于振动声发射噪声以及力信号的特征提取(this code is for energy of wpt Feature extraction such as Acoustic emission，vibration sound and force )

变速恒频风力发电系统的 自抗扰控制技术 (Variable speed constant frequency wind power system disturbance rejection control technology)

一个二进制PAM通信系统，使用滚降系数0.4的升余弦波形，速率4800bps，仿真早迟门的工作(A binary PAM communication systems, the use of roll-off factor of 0.4 or cosine waveform, rate 4800bps, early-late gate simulation work)

逆变器的调制方法有多种，如单极性调制，双极性调制，单极倍频调制等，此处是单极性调制，并给出单极性调制发生器(There are many modulation methods for inverters, such as unipolar modulation, bipolar modulation, unipolar frequency modulation, etc. This is unipolar modulation, and a unipolar modulation generator is given)
