Bayes辨识程序，系统辨识中应用，比较不错，希望大家能用到(Bayes identification procedures, the application of system identification, comparison is true, I hope everyone can use to)

说明：  一个ask调制解调的源程序，可以自己添加一些噪声进行仿真分析！(Ask modulation and demodulation of a source, you can add some noise to conduct their own simulation analysis!)

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

esprit 旋转不变技术来估计波达方向 最基本算法，能估计出波达方向，但特征值较难估计，有误差，按照现代通信原理最基本算法matlab编码。(esprit ESPRIT DOA estimates the basic algorithm can estimate the DOA, but difficult to estimate eigenvalues, margin of error, according to the basic principles of modern communication matlab coding algorithm.)

说明：  粒子群优化算法pso优化支持向量机svm(Particle swarm optimization algorithm pso optimization support vector machine svm)

图像插值程序，可以实现对图像的任意缩放，即可以图像尺寸改变为任意大小。(Image Interpolation procedures can realize arbitrary scaling of images, namely image size can be changed to any size.)
