摘要
频谱资源的日益紧张和利用率不高,是认知无线电得以发展的重大原因,文章讨论了认知无线电的体系结构,深入研究了当前认知无线电中的关键技术,对比分析了认知无线电各种频谱感知技术的优缺点,以及频谱管理等的新发展。
The spectrum resources become increasingly strained and the usage of the spectrum is not efficient ,This makes the cognitive radio has a major development .In this paper, we introduce the architecture of the cognitive and have studied of key technologies ,comparison of various methods of spectrum sensing, also introduce the new development of the spectrum management.
