Licensed user (primary user) detection has gained a great deal of interest recently on spectrum sensing strategies whereas unlicensed user (secondary user) detection must be a part of sensing with equal proportion of interest. This paper proposes a novel scheme that enables an efficient and robust spectrum sensing for both primary and secondary users detection. The proposed scheme is based on intentionally adding known noise at the sensing side. Then the sensing detector becomes insensitive to signal and noise types, and thus noise uncertainty problem is diminished. After sensing, the added noise is removed without affecting existing transmission on the channel. Although there have been several spectrum sensing methods, the proposed scheme is the optimal solution for spectrum sensing, to the best of our knowledge.</span></p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.21.6.13769">http://dx.doi.org/10.5755/j01.eee.21.6.13769</a></p>}, number={6}, journal={Elektronika ir Elektrotechnika}, author={Ozbay, Serkan and Ercelebi, Ergun}, year={2015}, month={Dec.}, pages={90-95} }
