We analyze sufficiency and optimality of energy detection (ED) for decision fusion. The considered scenario assumes on-off keying (OOK), statistical channel state information and a fusion center (FC) equipped with multiple antennas. The fading is modeled through zero-mean Gaussian mixtures (GM) to deal with arbitrary non-line-of-sight (NLOS) environments. Theoretical findings are supported by numerical simulations.
