一本介绍MIMO-OFDM的书，包括了MATLAB程序，非常适合做MIMO-OFDM仿真的参考书。(An introduction MIMO-OFDM books, including MATLAB program, very suitable for MIMO-OFDM simulation reference.)

应用Simulink搭建双储水槽系统，同时引入外部干扰进而可进行系统的模型辨识。(Application of Simulink to build dual storage tank system, while the introduction of external interference and thus available for model identification system.)

说明：  原理：以待处理的像素作为中心，取一个nXn的模板，在模板中选择k个与待处理像素的值最接近的像素，将这k个像素的均值替换原来的像素值。 假设n=3，k=5，调用方法：b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))
