In cognitive radio network (CRN), traditional energy detection algorithm has a bad detection performance in fading and shadowing environment. So cooperative spectrum sensing among cognitive radio nodes is needed in order to overcome these drawbacks. However it will result in a large demand of communication bandwidth on the control channel when the number of nodes is great. To solve this problem, this...
