Area 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.
