基于颜色对的方法的程序实现 　　具体程序实现如下：-Color-based approach to implementation of specific procedures for implementation procedures are as follows:

png格式的动画演示 比bmp或jpg更好 因为png格式的具有bmp的清晰 大小却又像jpg那么小，比bmp要小很多。 但这个是在wince上运行的 在windows xp下不能直接运行，可供参考。-png ? ?ê ? μ? ? ˉ ???ê ? ± èbmp? ?jpg ? ü o ???? a png ? ?ê ? μ? ? ?ó?bmpμ????ú

三维模型大多是用三角网格形式描述的，基于OpenGL和C++绘制了三角网格模型，并实现了与键盘和鼠标的交互，通过点击鼠标键和按键盘响应键，可以对模型进行旋转、缩放、移动等操作。

Cognitive radio frequency spectrum detection-The spectrum sensing of a wideband frequency range is studied by dividing it into multiple subbands. It is assumed that in each subband either a primary user (PU) is active or absent in a additive white Gaussian noise environment with an unknown variance. It is also assumed that at least a minimum given number of subbands are vacant of PUs. In this multiple interrelated hypothesis testing problem, the noise variance is estimated and a generalised likelihood ratio detector is proposed to identify possible spectrum holes at a secondary user (SU). Provided that it is known that a specific PU can occupy a subset of subbands simultaneously, a grouping algorithm which allows faster spectrum sensing is proposed. The collaboration of multiple SUs can also be considered in order to enhance the detection performance. The collaborative algorithms are compared in terms of the required exchange information among SUs in some collaboration
