资源描述 黑金开发板关于GUI的程序，保证可用，适合初学者使用。 图形用户界面是一种人与计算机通信的界面显示格式，允许用户使用鼠标等输入设备操纵屏幕上的图标或菜单选项，以选择命令、调用文件、启动程序或执行其它一些日常任务。与通过键盘输入文本或字符命令来完成例行任务的字符界面相比，图形用户界面有许多优点。图形用户界面由窗口、下拉菜单、对话框及其相应的控制机制构成，在各种新式应用程序中都是标准化的，即相同的操作总是以同样的方式来完成，在图形用户界面，用户看到和操作的都是图形对象，应用的是计算机图形学的技术

This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO. -This model is just an idea of testing MIMO. IEEE802.11n which will have. But I havo not seen the standard.
