Spectrum sensing is a central part in a cognitive radio and therefore a thorough design of a spectrum sensor is of highest priority. Here, a novel implementation of a spectrum sensing technique, using a generalized version of the Neyman Pearson test, is considered. This novel implementation overcomes the usual prerequisite of the known noise power. This benefit is achieved by normalizing the signal...
Cognitive radios require spectrum sensing. IEEE 802.22 defines constraints on conceivable spectrum sensing techniques. In order to fulfill theses constraints on the required detection probability and allowed false alarm probability, the signal sensing requires a certain sensing time period and an appropriately adjusted decision threshold. This manuscript presents a novel dynamic spectrum sensing scheme...
