采用差分阈值法对心电信号QRS波进行特征提取ecg0

《射频电路设计——理论与应用》一书课后习题第十章Matlab程序代码（完）("RF circuit design-- Theory and Application," a book OSCAR Exercises Chapter 10 Matlab code (END))

说明：  南航写的gps仿真器源码，用matalb编写的一个比较简单的GPS仿真器，供大家学习和参考。(China Southern gps emulator written source, matalb prepared using a relatively simple GPS simulator for them to learn from and reference.)

Z源与Boost电路结合的单相全桥逆变器的开环仿真(Z-Source Boost circuit with a combination of single-phase full-bridge inverter open-loop simulation)

说明：  在基于事件的情况下将分数阶PI-PD控制器离散实(The fractional order PI-PD controller is discretized based on event)

彩色图像批量转换为灰度图像并自动保存，刚刚写好的一个小程序(Batch convert color images to grayscale images and automatically save, just a small program written)

基于最简单的直接转矩控制的matlab程序框图，经试验，完全可以正常运转(Based on the most simple and direct torque control matlab block diagram, the test, can operate normally)

BEE COLONY OPTIMIZATION

这是ofdm的MATLAB仿真源程序，很好用(This is the MATLAB simulation ofdm source, useful)

A suitable algorithm suggested with wavelet compression for gray scale images based on one- and two-dimension combined hierarchical structure, in the sub-band which has been generated by the aid of several types of wavelet functions. It is shown that the using of combined based hierarchical structures allows us to reduce the calculations complexity of compression and decompression at constant values of compression coefficients

说明：  该算法连续系统的抗积分饱和的PID算法,用MATlab开发，能够管直接运行,可明显减弱几分饱和现象对系统稳定性的影响，当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。(The algorithm of the anti-continuous system saturated PID integral algorithm, developed using Matlab and can directly run the tube can be significantly weakened somewhat saturated phenomenon on system stability, when the control volume and settings deviation is larger, integral role in the abolition of so as not to cause too large integral role in the stability of the system lower.)
