diversity analysis in matlab

利用stft实现了跳频信号的跳周期估计 简单的进行了跳频信号的仿真，然后利用短时傅里叶变换对跳频信号进行分析，再对得到的时频矩阵提取时间平面，对时间序列去直流，进行傅里叶变换，最后实现得到跳周期。(estimates the hopping time of the sfh by stft )

DFT谱分析，加矩形窗与加hamming窗对比(DFT spectrum analysis, plus rectangular window hamming window contrast)

利用MATLAB 提取ECG 波形数据,从图像中采集心电波形非常有用。(extracting ECG data from images)

说明：  双电机模型用于汽车的搭载和嵌入，与其他汽车模型联合使用(The dual motor model is used for vehicle loading and embedding, and is used in combination with other vehicle models)

一个用simulink做的模糊PID自适应系统，通过三个模糊FIS：dkp,dki,dkd来分别控制Kp,Ki,Kd，以达到PID参数可自动调整的目的。(A simulink do with self-adaptive fuzzy PID system, through three fuzzy FIS: dkp, dki, dkd to control the Kp, Ki, Kd, in order to achieve automatic adjustment of PID parameters can be objective.)

matlab 中的3D模型的建立和分析，不少经典的使用。(3D model is used in the matlab)

HDB3扰码技术的matlab编程实现，自己的论文整理，计算机原理必备(HDB3 scrambler technology of matlab programs, their papers, computer principle is necessary)

无刷直流电机 伺服控制系统仿真 精华,对转向器等方面有用(The brushless DC motor servo control system simulation the essence of the steering gear and other useful)
