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

SolidGraph CAD System
SolidGraph is a full-featured system for 3D modeling of highly complex geometric objects. Sooner or later, everyone who works with computer graphics feels necessary to write his own editor. We want to show you one of the ways of writing a module application where the functions for creating new objects are distributed among plug-ins.

不用图形库函数的仿windows画图程序
这是最近做的计算机图形学实验,其界面是一个仿Windows下的窗口界面,程序具有较好的交互性。全部的图形函数都没有用C语言自带的图形库函数,所写的函数都是直接写屏实现的,模拟了大部分图形库函数的功能。但也有部分没有写出,如保存图形块的getimage()等函数。由于水平有限,还有部分功能没有实现,如保存或打开BMP图片等。等有了时间再说吧。算法什么的写的很潦草,都随便说说的,欢迎高手指点,希望与广大C语言爱好者共同学习讨论。
-No graphics library function like windows drawing program to do this is the recent experiment of computer graphics, the interface is an imitation of the window under the Windows interface, the program has better interactivity. All graphics functions are not used C language graphics library built-in function, written by direct write screen functions are achieved, the majority of simulation graphics library function function. However, some did not write, such as the preservation of graphical block getimage () function and so on. Due to the limited level, there are some features did not realize, such as saved or opened that BMP pictures. With time, etc. later. What algorithm is written in the scrawl, are casual, welcome expert guidance, I hope with the
