Cognitive radion attracted more attention as it access and use spectrum opportunity in communication. Energy detection is given more reseach as advantage of simple algorithm and without prior knowledge compared to other spectrum sensing. This paper study energy detection in keyhole channel when others do it in Rayleigh and other channels, and contrast to it's performance in AGWN. What's more, this paper persent cooperative sensing to offset deficiency of single secondary user detection in Keyhole channel.
