数字调制信号的产生与识别。产生数字调制信号，并汇出图像，比较直观。 通过分析解调的幅度、频率、相位来判断该信号的调制类型。(Generation and identification of digital modulation signals. Generates a digital modulation signal, and export the image, intuitive. To determine the modulation type of the signal through the analysis of the amplitude, frequency and phase demodulation.)

说明：  东华大学机器学习核密度估计大作业 第一部分是一个三维的彩色KDE估计图（最好用MATLAB画）；第二部分是测试图片的运动目标二值图像检测结果（运动员用白色像素，背景用黑色）(Big assignment of kernel density estimation for machine learning in Donghua University The first part is a three-dimensional color KDE estimation map (preferably drawn with Matlab); the second part is the detection result of the moving target binary image of the test image (athletes use white pixels, background use black))

卡尔曼滤波 现代滤波器的实现,matlab源码(Kalman filter to achieve a modern filter, matlab source)

It is a matlab sourcecodes for the calculation of refrective index of AlGaAs alloy. I think it is useful for the guys who need the accurate value of the refrective index. It can be expanded to the other semiconductor alloy if you have the related parameters.
