空闲频谱检测是感知无线电(CR)的关键技术之一。协作检测算法是空闲频谱检测的关键算法,早期协作检测算法方面的文献只是考虑了检测信道部分对检测性能的影响,而没有将报告信道对检测性能的影响考虑进去。推导了常用融合规则下引入错误报告概率对协作检测算法性能的影响,这对感知无线电的实际应用具有重要的参考价值。 Idle spectrum detection is one of the key technologies for cognitive radio (CR). Collaborative detection algorithm is the key algorithm of free spectrum detection. The literature of early cooperative detection algorithm only considers the influence of detection channel on detection performance, but does not take into account the impact of reporting channel on detection performance. The influence of error reporting probability under common fusion rules on the performance of cooperative detection algorithm is deduced, which has an important reference value for the practical application of cognitive radio.
