简单KNN算法，基于MATLAB，适合初学者。(simple Knn )

high voltage converter

说明：  OQPSK调制的仿真，给出了I和Q支路的BPSK调制信号图。窗函数可选矩形窗和升余弦窗。(OQPSK modulation simulation, given the I and Q branch BPSK modulation signal Fig. Optional rectangular window function window and the raised cosine window.)

I created a script that show how to remove repeatable noise with standard pattern in an image.

自定义的三次样条小波去噪程序，其中分解层数为4，阈值处理采用软硬阈值计算方法。(The three-dimensional spline wavelet denoising procedure is adopted, and the number of decomposing layers is 4, and the threshold is used to calculate the soft and hard threshold.)

This is the information about wavelett transform use in matlab

the image processing technique in obtaining the features present in the blood vessels of a retinal image is given

this code gives minimum peak to average power ratio. the technique used here is adding peak reduction carriers

基于最小二乘支持向量机对传感器的非线性系统用MATLAB软件进行仿真建模程序(Based on least square support vector machine (SVM) of the nonlinear system of sensor with MATLAB simulation modeling software program)
