—A parallel, multi-resolution spectrum sensing technique that is amenable to multiple-antenna cognitive radios is introduced. We show that for energy-detector-type spectrum senso...
Abstract--We consider cooperative spectrum sensing for cognitive radios. We develop an energy efficient detector with low detection delay using sequential hypothesis testing. Seque...
—One of the main requirements of cognitive radio systems is the ability to reliably detect the presence of licensed primary transmissions. Previous works on the problem of detect...

—Cooperative spectrum sensing is attracting more attention in Cognitive Radio networks. This paper proposes a fully distributed consensus-based cooperative spectrum sensing schem...
—In this paper, we propose several spectrum sensing methods designed using the generalized likelihood ratio test (GLRT) paradigm, for application in a cognitive radio network. Th...
