Abstract:The development of radio technology and the expansion of business scope make communication and other fields increase the demand for spectrum sensing technology of cognitive radio. Spectrum sensing technology resources have become important factors affecting the development of national economy and the progress of communication industry,increasing the research and application of spectrum sensing technology has become the key to the progress of the industry. In this paper,the concept of spectrum sensing technology,technical premise and design challenge are expounded. Several typical spectrum sensing techniques are analyzed,and the key points of cognitive radio spectrum sensing technology are studied. The aim of this paper is to analyze the direction and difficulties of the development of cognitive radio spectrum sensing technology,and to lay a theoretical and data base for the long-term development of spectrum sensing technology.

Keywords:cognitive radio;spectrum sensing technology;intelligent communication
