matlab做的有源电力滤波器的仿真模型，做的有点乱。(matlab to do the simulation model of active power filter, do a bit messy.)

车牌定位原代码，具有较好的定位功能，实时性较好(License plate location of the original code, and has good positioning capabilities, better real-time)

说明：  用MATLAB语言编程计算半波对称振子场图，电流分布和输入阻抗(Using MATLAB programming language calculated half-wave field in plane symmetric oscillator, current distribution and input impedance)

实现了跟踪算法里的UKF滤波算法，统计了该滤波算法性能 (UKF in the tracking algorithm, statistical filtering algorithm performance)

一个m函数，可以读取GprMax2d的模型数据，将雷达正演模拟的模型的刨面数据读出来(A function of m, can be read GprMax2d model data, radar forward simulation model of the planing surface data read out)

Signle side band Modulation Matlab code

matlab信号的DOA估计 music算法 加入循环(bpsk music cyclic doa)

展频PLL时钟（SSC）产生电路，可以产生三角波、正弦波或者单频载波(Delta_Sigma Modulator, to be used in TXPLL with SSC modulation. this program simulates the Spread spetrum clocking scheme. the SSC can be set to triangle wave or sinewave, or you can also set it to be constant frequency which without SSC. the relevant parameters is programmable. )

实序列FFT快速算法，用N点FFT计算2N点实序列的FFT，比直接进行2N点FFT运算减少一半运算量。(Real sequence FFT fast algorithm, using N-point FFT calculation 2N point real sequence of FFT, than the direct 2N-point FFT computation halved.)

Stochastic resonance，SR）的概念最初是由Benzi等人提出并用于解释第四纪冰川问题，此后用于描述一种现象──非线性系统中内噪声或外噪声的存在可以增加系统输出的响应。这里一共有在网上下载的一共7种不同的程序，供大家分析参考(The concept of Stochastic resonance (SR) was first proposed by Benzi et al. And used to explain Quaternary glaciation. After that, it is used to describe a phenomenon -- the presence of internal noise or external noise in nonlinear system can increase the response of the system output. There are a total of 7 different programs available for download on the Internet for people to analyze and refer to)
