Co-operative cyclo-stationary feature detection with universal filtered multi-carrier spectrum sensing for cognitive radio network
R. Dimple Dayana, R. Kumar · 2016
The Cognitive Radio is a smart wireless communication system that provides awareness about the radio frequency spectrum of its surroundings and rapidly reconfigures its operating parameters dynamically. It is a methodology to use the currently available spectrum momentarily without interfere the licensed user. This paper focuses on the challenges associated with network spectrum sensing, by employing the methods of signal detection through Cyclo-stationary Feature Detection (CFD) using the co-operative system. The analysis of new co-operative CFD with Universal Filtered Multi-Carrier (UFMC) transceiver for cognitive radio networks is done. The simulation result proves that this method of sensing is optimal for signal detection under low SNR.
