摘要：

Spectrum sensing is a functionality that enables network creation in cognitive radio technology. Spectrum sensing is used for building situational awareness and knowledge, which in turn can be used to improve the usage of radio resources and to adjust network parameters in case of jamming, interference from legacy systems, or decreased link quality caused e.g. by changing positions of radio nodes. This paper presents results of comparison tests between cooperative centralized sensing and local sensing. All tests were performed in a simulator, which was developed in Matlab/Simulink environment.
