现代通信系统与matlab（程序）proakis版(Modern communication systems and matlab (process) proakis version)

基于matlab软件上的功率因数校正课件，对于初学者有很好的帮助(Matlab software based on the power factor correction courseware, there is a good help for beginners)

数值分析课程设计，内附MATLAB源码和word,用三次样条插值设计中英文签名，双三次做改进； 采用交互式界面进行操作，用鼠标点击获取名字大致的数据点 三次样条插值算法：可产生二阶光滑度，即二阶导数连续签名图样(Numerical analysis of curriculum design, enclosing the MATLAB source code and the word, using cubic spline interpolation design in English and Chinese signatures, double the three to do to improve using an interactive interface to operate with a mouse click to obtain the name of the data points roughly cubic spline interpolation algorithm: can generate second-order smoothness, that is, a continuous second derivative sign pattern)

这是一个图像信噪比计算的小程序，不是峰值信噪比，请注意。(This is a small program SNR calculation, not the peak signal to noise ratio, please note.)

隔离准Z源逆变器的开环控制，希望对初学者有些帮助。(Isolation the open-loop control of Z source inverter, and want some help for beginners. )

说明：   duhen迟滞模型的MATLAB语言实现，这是自己对照duhen迟滞模型的数学表达式编写的，已经运行过，完全正确(On the hysteresis)

DC-DC升降压电路,主要实现升压和降压功能，采用PI电压电流双环控制(DC-DC buck-boost circuit, the main step-up and step-down function, using the PI voltage and current loop control)

说明：  该代码是由matlab编写的。粒子群是一种快速优化方法。能大量节省计算机运行时间。(The code is written in matlab. PSO is a fast optimization method. It can save computer time.)

利用平均位移法（AD）求取混沌时间序列的延迟时间（tau），参考文献是吕金虎所著(The average displacement (AD) to strike a delay time of the chaotic time series (tau), Reference Lvjin Hu book)

对阵列进行二维谱分析时使用, 用于信号估计,阵更信号处理(Spectral analysis of two-dimensional array used for signal estimation, array signal processing is more)
