A robust multistage spectrum sensing model for cognitive radio applications
K Mourougayane, B Amgothu, S Bhagat… - … -International Journal of …, 2019 - Elsevier
Spectrum sensing is widely exploited in Cognitive Radio (CR) to detect and utilize the
unoccupied, underutilized frequency bands. Reliable spectrum sensing is an essential
prerequisite for the successful applications of CR. In this paper, a robust multistage detector
suitable for tactical CR applications is presented. The proposed method utilizes two parallel
detectors for low and high SNR bands. Energy Detector (ED) and Singular Value based
Detector (SVD) are used in the high SNR band and Cyclostationary Feature based Detector …
