Energy detection of primary signals over η - μ fading channels

Abstract

In this paper1, 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, results are extended to two diversity reception cases such as maximal ratio combining (MRC) and square-law combining (SLC) techniques with independent fading channels. Detection performance is discussed with receiver operating characteristics (ROC) curves. Our analysis is validated by numerical and simulation results.
