Simplified Performance Analysis Of Energy Detectors Over Myriad Fading Channels:Area Under The Roc Curve Approach

Shumon Alam
2012 International Journal of Wireless & Mobile Networks  
The detection performance is characterized by the area under the receiver operating characteristic (ROC) curve (AUC), which is a simple statistical performance measuring metric that varies between 0.5  ...  Our proposed frameworks with AUC performance metric inthe myriad fading environments provide new ways of characterizing and evaluating energy detector's performance.  ...  Such a measure is the area under the ROC curve (AUC) which varies between 0.5 (poor performance) and 1 (good performance) [5] .It is a single scalar value of expected performance and represents the probability  ...
