摘要 在多用户认知无线电系统中,针对认知无线电用户合作频谱感知中联合检测性能的提高与控制信道带宽受限的矛盾,提出了一种基于能量检测的合作频谱感知方法。该方法放弃携带信息量较少的感知信息,并将携带信息量较多的感知信息量化后传送至数据融合中心。这种方法在兼顾认知无线电频谱感知性能的前提下,有效降低了控制信道开销。 In cognitive radio systems,a cooperative spectrum sensing method is proposed,which takes into account the relationship between control channel burden and the performance of detectors.By taking out the signals with less amount of information and quantizing the signal with more information,the accuracy of spectrum sensing and cost of the control channel are compromised in this approach.
