signal preprocessing

对标幺化感应电机的控制，依次分块地对磁通，转矩，转矩设计控制器，并对模型简化和未简化的情况做对比，适合于对感应电机控制各个环节的控制有更深的理解。(Induction motor control, in turn block the flux, torque, torque design of the controller, and the model is simplified and not simplified contrast, is suitable for the control of all aspects of a deeper understanding of the induction motor control. The outcome of the study in the experimental class)

通过四阶差分运算，理想的去除粗差(Four order difference operation, ideal removal of gross error)

说明：  q-learning 实现 栅格迷宫路径规划，附带随机迷宫生成代码(Q-learning to achieve grid maze path planning, with random maze generation code)

说明：  主要指令：butter（产生巴特沃斯滤波器）；freqz（绘制幅频、相频曲线）；zplane（绘制零、极点图）；ss2zp（状态方程变零、极点）；zp2tf（零、极点变分式多项式）。(Main instruction: butter (produced bart wo filter) Freqz (draw amplitude frequency, phase frequency curve) Zplane (draw zero, poles chart) Ss2zp (state equation is zero, poles) Zp2tf (zero, pole change fraction polynomial). )

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)

this small matlab code is used to design butter worth filter.

This the source code for the first chapter where you can try to understand

该程序可以实现图片的拖拽，放大和缩小等简单的处理。(The program can drag images, zoom in and out such simple treatment.)

fastICA,进行串行盲源分离的一种不错的方法(fastICA, serial blind source separation method for a good)

This is remote sensing image enhancement project. Which deals with image enhanement and noise removal from rsi images. It also uses different edge detection techniques for image enhancement
