Area 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.
