PCA

这段代码是最近调试的一段ECG滤波检波的软件，它实现了对一段ECG数据的GAUS变换滤波，能较为准确的测定出P，Q，R，S，T等关键波的长度及特征。有兴趣的可以看看(This code is the latest section of ECG filtering detector debugging software, which implements the ECG data on a GAUS transform filtering, can be more accurate determination of the P, Q, R, S, T, and the length of the critical wave characteristics. Interested to see)

说明：  this is simple signal processing matlab code

MQAM信号的调制识别的误码率，眼图，和星座图的matlab代码，很有用的一个程序(MQAM modulation recognition error rate signal eye diagram, constellation mapping matlab code, very useful program)

MATLAB code that simulates our proposed Max Likelihood Estimation of P matrix using EM algorithm

案例为利用最有控制原理，实现对机械手转台的最优控制。运用matlab，以及simulink仿真实现。(Case for the use of the most control theory, to achieve optimal control of robotic turntable. Use matlab, simulink simulation, and implementation.)

This is a matlab simulation for CPM which is using viterbi decoder to decode the signal. There is pulse shaping used in this file and the default signal is assumed to be rectangukar

多变量极点配置，自动控制原理，matlab程序，希望对大家有用(Multivariable pole assignment, Automatic Control Theory, matlab procedures useful for everyone)
