很好的关于认知无线电的综述，对频谱感知，频谱管理以及动态接入方法进行了很详尽的阐述-Good overview on cognitive radio, spectrum sensing, spectrum management, and dynamic access methods are very detailed exposition

在认知无线电中，频谱感知频谱分配是两个主要问题，而动态频谱接入是理解频谱感知的关键。-In CR, spectrum sensing and spectrum allocation is the major problem, but the dynamic spectrum access is the key to understand spectrum sensing.

Cognitive radio allows unlicensed users to access licensed frequency bands through dynamic spectrum access so as to reduce spectrum scarcity. This requires intelligent spectrum sensing techniques like co-operative sensing which makes use of infor
