Abstract

Cognitive radio (CR) technology is an emerging technology to improve the utilization of radio spectrum. Cooperative sensing is used to enhance the efficiency of the cognitive radio network (CRN). In this paper, we consider the probability of detection or false alarm under constant detection rate and constant false alarm rate scenarios over the imperfect reporting channels. We illustrate that all secondary users in the network don´t achieve the optimal performance in cooperative spectrum sensing.
