On the Energy Detection of Unknown Signals Over Fading Channels
Fadel F. Digham, Mohamed‐Slim Alouini, M.K. Simon · IEEE Transactions on Communications · 2007
This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-form expressions for the probability of detection to those recently reported in the literature. Detection capability is boosted by implementing both square-law combining and square-law selection diversity schemes
