随机感知的机会频谱接入，方法思路较简单-randomly sense channel of opportunistic spectrum access in cognitive radio

认知无线电中频谱感知是其应用的基础和前提，文章是最新频谱感知的形式-Spectrum sensing in cognitive radio applications is the basis and premise, the article is the latest form of spectrum sensing

频谱感知是认知无线电的一个重要前提，而能量检测法则是比较成熟的频谱感知算法。它可以有效地凡发现频谱孔，使得认知无线电与周围通信环境相适应-Spectrum sensing cognitive radio is an important prerequisite, and the law of energy detection of the spectrum is a more mature perception algorithm. Where it can be found in the sp
