Figure 4From: 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 = - 7 dB andσ f = 0 dB. (a) σ Δ σ =0 dB and (b) σ Δ σ =5 dB. The figure shows the plots of the area under the ROC curves (AUCs) to analyze the sensitivity to shadowing for the case when P0 = -7 dB and σ f = 0 dB. Further details about this figure are given in subsection with heading Experiment 3 in Section 6.Back to article page
