Abstract

Coordinated spectrum sensing ensures Cognitive Radio systems to get the usability of every channel within the entire spectrum of interest by assigning terminals to detect different channels simultaneously. This letter proposes an optimized channel-assignment strategy for coordinated spectrum sensing based on an Iterative Hungarian Algorithm. Simulation results show that the proposed strategy performs excellently in improving the overall sensing performance of the system.
