Cooperative Spectrum Sensing With Data Mining of Multiple Users’ Historical Sensing Data
IEEE Access, 2016 Under the case of exponentially growth of wireless services and the scarcity of spectrum resources, cognitive radio (CR) has been proposed to access licensed channels opportunistically, and thus improve spectrum utilization.

Evaluating Cooperative Spectrum Sensing: A Hardware-in-the-Loop Approach [PDF]
In this work, we present a hardware-in-the-loop evaluation of cooperative spectrum sensing using eigenvalue detection. Single-node spectrum sensing is unreliable as it is susceptible to hidden node problems.
