Abstract

Cognitive Radio (CR) is proposed to solve the spectrum scarcity problem caused by the explosive growth of wireless devices and the fixed spectrum allocation policy. Spectrum Sensing is a fundamental method in CR. Cooperative Spectrum Sensing (CSS) can effectively improve detection accuracy. Numerous works considering perfect reporting channels exist. However, imperfect reporting channels have not gained enough attention until now. In this paper, we investigate imperfect flat Rayleigh fading listening and reporting channels. We use channel state information to assist Fusion Center (FC) to make final decisions, and propose several channel-information-based MRC decision rules. Finally, traditional hard decision rules are compared with our proposed channel-information-based MRC decision rules. Our Selection-based MRC decision rule can achieve the lowest total error rate.
