Cognitive radio system provide the user 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 paper, the authors 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.
