层析分析法的一个简明程序，方便的求出最大特征值以及w0 wi。希望能帮助大家(Chromatography analysis of a simple procedure, easily find the largest eigenvalue, and w0 wi. Hope to help you)

本文利用软件相移技术得到相互正交的参考正弦波信号；通过互相关算法，完成了软正交矢量型LIA相关器的具体实现；利用该方法实现了对微弱信号幅值和相位的检测，有效地抑制干扰，减少了硬件电路成本。通过Matlab仿真，验证了该算法具有一定的优越性。(In this paper, the software technology is orthogonal to the phase shift of the reference sine wave signal through cross-correlation algorithm to complete the implementation of soft orthogonal vector LIA correlator achieved using this method for detecting a weak signal amplitude and phase, effectively suppress the interference and reduce the cost of the hardware circuit. By Matlab simulation show that the algorithm has certain advantages.)

Motion stimation_ This gets the absolute difference of any pair of video frames.

本程序及链路是模拟了瑞利信道下，用RLS算法还原出发送端的的有效信号。通过simulink实现，同时调用RLS的m函数。(This procedure and the link is simulated Rayleigh channel, the to restore valid signal to the sending end of the RLS algorithm. Simulink realization, while m function call RLS.)

prony算法做相关仿真，可自行更改pe，也可调整p。(Prony algorithm is used to do related simulation, and PE can be changed or P can be adjusted.)

汽车车牌的图像识别。 根据车牌凸角轮廓特征，采用MPP算法进行车牌倾斜校正；采用彩色图像分割方法，最大限度的去除图像噪声干扰；设计了基于神经网络的多种彩色背景车牌字符识别方法，取得了良好的效果。(Image recognition of vehicle license plates. According to plate convex contour feature, the use of MPP plate tilt correction algorithm using color image segmentation method, the maximum removal of image noise designed based on a variety of colored background neural network method for license plate recognition, and achieved good results.)
