Abstract
- In order to observe the occupancy status and to locate spectrum holes, the energy spectrum sensing feature plays a key role in the efficiency of cognitive radio networks. Usually, spectrum allocation occurs through a licensing process. Users of Cognitive Radio are unlicensed users who dynamically locate unused licensed spectrum for their own use without interfering with licensed users. Spectrum sensing, spectrum decision-making, spectrum sharing and spectrum mobility are four key functions of cognitive radio systems. In this paper we study the spectrum occupancy measurements and SNR threshold in a new perspective. The thresholds of the spectrum are detected using low SNR phenomenon. The decision threshold plays a crucial role in assessing the presence or absence of the primary users signal. The configuration of the measuring setup and other issues relating to the measurements of frequency and Detection of SNR threshold were addressed.
