Abstract
The cognitive radio (CR) technique is a useful tool for improving spectrum utilization by detecting and using the vacant frequency bands while avoiding interference to the primary user (PU). In this paper, we propose cooperative spectrum sensing scheme using individual sensing credibility based on double adaptive thresholds for cognitive radio network. In the proposed scheme, a few local sensing information that satisfies the credibility condition will be reported to the Fusion Center (FC). By this way, CR users can save the power consumptions and the collision problem in the control channel is reduced . In addition, by ignoring the local sensing information with low credibility, the global sensing performance can be improved.
