中值滤波是一种非线性滤波方法,在一定条件下可以克服线性滤波器处理图像细节模糊的问题,但是对点、线、尖顶等细节较多的图像,则会引起图像信息的丢失[3].中值滤波的基本思想是把局部区域的像素按灰度等级进行排序,取该邻域中灰度的中央值(中值)作为当前像素的灰度值

这是一个适合于MIMO－OFDM系统信道的分解方式GTD和GMD的源代码，并附有相关的文章，希望对大家有用。(this is a suitable for MIMO-OFDM channel decomposition method GTD GMD and the source code , with related articles, we hope that the right useful.)

说明：  Description : This package includes a configurable Simulink model for three different types of DC-DC converters (Buck, Boost and Buck-Boost converters) with a PWM PI controller. The example provided shows a case to boost voltage 5 volts to 25 volts. It can be used to learn DC-DC converters and their control. The model itself also provides an example how to mask a subsystem in Simulink. A HTML and a pdf files are provided to explain the principles of the unform Simulink model for three different types of DC-DC converters. The model does not require other Simulink blocks, such as SimPowerSystems.
