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

this file is python code implement spectrum sensing on gnuradio by usrp b210

matlab程序，核函数方法，可用于认知无线电频谱感知中(kernel function method for Spectrum sensing in cognitive radio)

频谱感知功率对平均可实现吞吐量的影响，随着指数的增长，平均可实现的吞吐量显著减少(The influence of spectrum sensing power on the average achievable throughput. With the exponential growth, the average achievable throughput decreases significantly)
