| Abstract: | This paper mainly studies the perception and location of small-scale mobile primary users in cognitive radio networks. Firstly, the concept and the research status of cognitive radio are briefly introduced, and the characteristics of large-scale and small-scale primary users are compared and summarized. Secondly, the difficulties to sense the small-scale primary users are described. The perception and location technologies for the small-scale primary users are classified. And the advantages and disadvantages of different location methods using different spectrum perception technologies are discussed. Finally, the key research directions for sensing small-scale mobile primary users in cognitive radio networks are given. |
