y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

this function is used for resizing the cropped images got the process of character extraction for the first step of build a ANN. This is useful because it can resize a lot of images in one folder.

实现加权最小二乘拟合，经典的系统辨识方法，很管用(Achieve a weighted least-squares fitting, classical system identification methods, it is useful)

OFDM通信系统，内容相当全面，希望对大家有用！！(OFDM communication system, the content is very comprehensive and we hope to be useful! !)

直方图均衡化是指将一幅图像的像素值均匀地分布在图像的各个区间上，从而是图像的视觉效果得到改善。(Histogram equalization is an image pixel values evenly distributed in various intervals in the image, which is to improve the image of the visual effects.)
