Spectrum Sensing Technique based on CAF and Third 3rd Order Cumulant for Cognitive Radio

Abstract

Cognitive radio system provide us a solution for spectrum congestion problem, but the effectiveness of the system is only depends on the technique used for spectrum sensing, that how effectively the detection is performing at very low SNR. In this research paper we proposed a technique of spectrum sensing based on CAF and third order cumulant. And the proposed algorithm effectively able to detect the presence of primary user at very LOW SNR, as compared to existing technologies present in literature.
