Performance analysis of energy detector over η − μ fading channel: PDF-based approach

The performance of an energy detector is analysed over an η-μ fading channel using the probability density function (PDF) of the received instantaneous signal-to-noise ratio. The η-μ is a generalised multipath fading channel that describes the non-line-of-sight wireless communications scenario. Novel, general, exact and closed-form analytic expressions for both average detection probability and the average area under the receiver operating characteristics curve are derived.
