In this paper, energy detector's performance over the wireless channels with composite multipath fading and shadowing effects is analyzed using the area under the receiver operating characteristic (ROC) curve (AUC) in contrast to the conventional ROC measurement. AUC is a single statistical parameter which can be used to describe energy detector's performance more meaningfully. An energy detector...
The performance of collaborative spectrum sensing using censored energy detection is analyzed. Unlike the conventional energy detector that applies the measurements from the interested band directly to the decision-making process, the censored energy detector selects the measurements at different collaborating users by comparing them with two pre-determined limits before applying them to collaborative...
In this paper, the performance analysis of an energy detector is exploited under the η - μ fading channel model. The received unknown signal at the energy detector is considered as the primary signal transmitted by a primary network user (e.g. cognitive radio network). This research is focused on derivation of the closed-form average detection probability over the η - μ fading channel model. Further,...
The energy detector (ED) is one of the spectrum sensing techniques that is used in the cognitive radio networks to detect the presence of the primary user (PU) in a certain spectrum band. This technique assumes that the PU is either present or absent during the sensing time. However, the ED's performance degrades in a scenario when the PU is absent and then appears during the sensing time. The ED's...
