Energy detection is the most widely used technique in cognitive radio networks to enable opportunistic spectrum access. In this paper, the problem of energy detection of an unknown deterministic signal over fading channels is revisited. More particularly, a new closed-form mathematical expression is derived for the average probability of detection of the energy detector (ED) over $${\upalpha }-{\upmu...
This paper addresses the problem of energy detection of an unknown deterministic signal over a general fading channel model. More particularly, a closed-form mathematical expression is derived for the energy detector's probability of detection over α-μ generalized fading channel with selection combining diversity reception. The derived expression can be used to study the performance of energy detector...
