A blindly collaborative spectrum sensing algorithms in fading environments

Abstract

Spectrum sensing is an important part of cognitive radio networks. The performance of the adopted spectrum sensing method is very important. When the primary user and the cognitive use rare in operation simultaneously in fading environments, performance of spectrum sensing is damaged. In this paper we quantify performance of blind spectrum sensing in fading environments and study effect of collaboration. Simulation results show that the proposed method is feasibility and lesser number of collaborating cognitive users can be needed to attain better performance of collaborative spectrum sensing in fading environments.
