In cognitive radio networks, secondary users need to conduct spectrum sensing to properly detect the presence of primary signals that may have much lower power than noise plus interference power. In such a case, time-varying noise plus interference, which is briefly called noise uncertainty in this paper, can substantially degrade the sensing reliability of(More)
This article presents the latest status and achievements of the IEEE Communication Society (ComSoc) Standards for Dynamic Spectrum Access Networks (DYSPAN), formerly IEEE Standards Coordinating Committee 41, that develops standards in the areas of dynamic spectrum access, cognitive radio, interference management, coordination of wireless systems, advanced(More)
