Energy detection of unknown signals with diversity reception in λ—μ fading channel

In this paper, we obtained the closed form analytical expression for the average detection probability of the energy detector in terms of series form expression over λ - μ fading distribution. We start with the no-diversity case, then further results are extended to two diversity reception cases such as square-law-selection (SLS) and collaborative detection case. Since arriving analytical expression is used for the obtaining the different fading distributions of λ - μ fading channel. The performance analysis of energy detection is also discussed with the receiver operating characteristics (ROC) curves. Our closed form expression is validated by numerical results.
