Figure 2From: Spectrum sensing with spatial signatures in the presence of noise uncertainty and shadowingArea under the ROC curve (AUC) for analyzing the sensitivity to noise power uncertainty: σ X = 0 dB,N = 1 0 0,M = 2 5 0,P 0 = - 7 dB andσ f = 0 dB. In this figure, we plot the area under the ROC curves (AUCs) to analyze the sensitivity to noise power uncertainty. Further details are given in subsection with the heading Experiment 2 in Section 6.Back to article page
