Energy sensing parameterization criteria for cognitive radios
Energy-based sensing (EBS) has been a topic of strong research in the last years due to its importance to Cognitive Radios (CRs). While EBS has been used in several works, different parameterizations have been adopted. In this work we compare different parameterization criteria to determine the decision threshold to the energy detector. We compare their performance through simulations by characterizing the interference caused to primary users and the throughput achieved by the secondary users. We also assess their relative performance.
