A useful source for car license plate recognition program to learn

This function alculates Fourier Amplitude spectra of the time series of uncorrected acceleration and velocity depending on the FFTformat argument and produce a plot.Visual inspection of the fas is helpful for setting a low cut frequency in filter design and implementation.

基于导频的频偏估计算法，经典Classen算法，亲测课实现(Frequency Offset Estimation Algorithm Based on the pilot, classic Classen algorithm, pro-test lesson realization)

这是一个多目标非齐次方程最优解的的问题，涉及加权及一元二次方程(This is a multi-objective non-homogeneous equations of the optimal solution of the problem, and a quadratic equation involving a weighted)

编写了一些插值所用源代码，和部分拟合，利用matlab 来实现，对于不同种类，给出不同解决方法。(The preparation of a number of interpolation used in source code, and some fitting, use matlab to achieve, to different types, different solutions.)

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

Matlab中的ePHASORsim的IEEE 39节点数据文件 (ePHASORsim basic model for balanced systems IEEE 39 bus)

三相并网逆变器下的LCL滤波器的谐波分析 给出逆变器输出电压和网侧电流的各次谐波表达式及其所占基波分量。 (lcl lcl lcl lcl)

用matlab对2fsk信号进行调制和解调(2fsk signal using matlab on the modulation and demodulation)

采用simulink对duffing和lorenz混沌系统进行仿真,然后又对lorenz混沌系统的进行延时反馈控制和同步控制,另外还有一个基于simulink的滑模控制,实现方便,效果不错!(Duffing using simulink for lorenz chaotic systems and simulation, and then lorenz chaotic systems on the conduct of delayed feedback control and synchronization control, there is another of the sliding mode control based on simulink to realize the convenience, good results!)
