Abstract :
This paper shows decision fusion rules for Cognitive Radio (CR) Networks under Nakagami-m fading channels. Due to detection performance limitation of the secondary users based mixed fusion rule, a new Likelihood Radio Test (LRT) fusion rule was proposed. Theoretical analysis and simulations show that the new fusion rule has better detection than conventional fusion rules.
