频谱感知协作检测方法仿真研究

Research on Simulation of Cooperative Spectrum Sensing

在认知无线电系统中,认知无线电用户需要快速准确地检测出主用户及其闲置的频带。本文就一种利用两个认知用户协作感知频谱的检测方法进行仿真研究,结果表明,它可以减少检测时间和增加检测的灵敏度。

In cognitive radio systems, cognitive radio users need to quickly and accurately detect the primary user of the band and its idle. This paper presents a cognitive use of the two user cooperation perception test new methods of the spectrum, can reduce testing time and increase detection sensitivity.
