Abstract
Cooperative spectrum sensing can achieve better detection performance by enabling Cognitive Radio (CR) users to report local sensing information for further combining. In the initial setup phase that the CR users are performing spectrum sensing, idle communication channels without the licensed user signal have not been well identified and the reporting bandwidth is quite limited. In this chapter, bandwidth-efficient cooperative spectrum sensing in a multiuser CR network is addressed. Based on the optimal structure with likelihood ratio test, a general approach is introduced that CR users simultaneously report individual sensing information to a combining node through the common control channel. The optimal design of local processing functions at the CR users and final decision rule at the combining node is discussed based on Bayesian criterion when the reporting channel is noisy and experiences fading. Calculation of probabilistic information involved in our design is given as well. In the proposed approach, the bandwidth required for reporting does not change with the number of cooperative users. Given proper preprocessing at individual users, our design maintains reasonable performance with the superposition of sensing data at the combining node. Simulation results also demonstrate the effectiveness of the proposed approach.
