To support high definition television (HDTV), the revision of DVB-T, the terrestrial digital video broadcasting standard, has recently been developed under the abbreviation DVB-T2. The provision of the anticipated high data rate services requires a highly accurate synchronization and frequency acquisition and tracking. Setting out from the procedure defined by the DVB-T2 implementation guidelines...
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...
