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

平滑文字滚动示例 这个文字滚动控件比较不错，滚动比较平滑，没有闪烁现象，支持左右水平、上下垂直滚动。【向左滚动样式一】是循环连续滚动，【向左滚动样式二】则滚动到左端时停止一下继续滚动，【向上滚动样式一】也和前面差不多。-Smooth text scrolling text scrolling control sample in this comparison is true that relatively smooth rolling, no flicker phenomenon, about the level of support, up and down vertical scrolling. [1] style scroll to the left is the cycle of continuous rolling, rolling left style [2] then scroll to the left when you cease to continue rolling, rolling upward [Style] also in front of an almost.
