User Identification Methods in Cognitive Radio Networks
Spectrum sensing is the process of detection of the user whether it is present or absent. Spectrum Sensing is the key role in Cognitive Radio (CR) Networks and thus improving spectrum utilization. The major issues that may arise in spectrum sensing are Probability of false alarm (Pfa) and Probability of miss detection (Pmd). An analytical comparison is proposed between two of Non-Cooperative detection methods in the spectrum sensing. In this paper, an attempt is made to identify a better detection method based on high Probability Detection (PD).
