Abstract

In this letter, we develop closed-form analytical expressions for the false alarm and missed detection probabilities of a cooperative spectrum sensing (CSS) scheme using cognitive radio (CR) nodes that are equipped with improved energy detectors (IEDs), employ receive antenna diversity, and operate over Hoyt (Nakagami-q) or Rician (Nakagami-n) faded sensing channels. The derived expressions are validated through extensive simulations.
