This is a simulink model for three phase square wave inverter

T.Schmidl & D.Cox算法给出了不同信噪比下，T.Schmidl 和D.Cox 提出的算法的定时测度图

图像显示程序，可以把txt像素文件显示成图像。(Image display program, and txt pixel file can be displayed as an image.)

pca principal component analysis with medical image(principal component analysis with medical image can make the dimension of the image as short as possible which is easy for us to compare their similiarities)

Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate.

说明：  建立并绘制任意信号的模糊函数。已在巴克码，线性调频，脉冲信号中测试过。(This program estimates and plots the ambiguity function for any signals. I have tested it for the Barker code, chirp signal, pulse signal. for good results the length of the input vector (Ut)should be more than 7. Example- a rectangular pulse should be described as[1 1 1 1 1 1 1]. Please, give your suggestions. it is made with the help of "xcorr" function (Author: R. Losada) in MATLAB and Ilia Iliev from TU-Sofia )

说明：  可以识别电子文档,图片和手写的英文字母,用MatLAB打开即可(It can recognize electronic documents, pictures and handwritten English letters. It can be opened with MatLAB.)
