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

用matlab检测二值图像的边缘.二值图像 binary image 每一像元只有两种可能的数值或灰度等级状态的图像。 其实就是单色图像。 除了黑，就是白，没有中间过渡，没有灰度的图像。 要么黑，要么白，而且所有的黑都是一个色。
-Detected by matlab binary image of the edge. Binary image binary image for each pixel there are only two possible values, or gray-scale image of the status hierarchy. In fact, the image is monochrome. In addition to black, is white, there is no transition between, no gray-scale images. Either black or white, and all black is a color.
