Abstract--Cognitive radio networks require fast and reliable spectrum sensing to achieve high network utilization by secondary users. Current optimization approaches to spectrum se...
This paper considers cooperative spectrum sensing in Cognitive Radios. In our previous work we have developed DualSPRT, a distributed algorithm for cooperative spectrum sensing usi...
—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...
