Figure 3From: Spectrum sensing with spatial signatures in the presence of noise uncertainty and shadowingArea under the ROC curve (AUC) for analyzing the sensitivity to shadowing: N = 1 0 0 andM = 2 5 0,P 0 = - 1 6 dB andσ f = 0 dB. (a) ROC curves of σ Δ σ =0 dB. (b) ROC curves of σ Δ σ =5 dB. In this figure, we plot the area under the ROC curves (AUCs) to analyze the sensitivity to shadowing for the case when P0 = -16 dB and σ f = 0 dB. Further details about this figure are given in subsection with the heading Experiment 3 in Section 6.Back to article page
