摘　　要：作为认知无线电核心和基础的频谱感知,自从认知无线电的概念提出就受到了高度关注。众多学者和研究机构进行了大量卓有成效的研究,取得许多有价值的研究成果。根据近几年频谱感知的发展状况,对现有的频谱感知技术进行系统总结归纳,从单点检测、合作检测以及检测策略等三方面介绍各种频谱感知方法研究进展和频谱感知算法在现有标准中的应用。最后阐述频谱感知存在的问题以及下一步发展方向。Spectrum sensing, as the kernel and base for cognitive radio, was researched widely since cogni tive radio was proposed. Many valued results were achieved thought hard work of many experts and insti tutes. According to development of spectrum sensing, spectrum sensing technologies are summarized systematically, including single user detection, cooperative detection and detection strategies. And then, some applications of spectrum sensing are introduced based on IEEE standards. Finally, the paper is coneluded and some existing problem and future research are described.
