DVB-T candidate power detector for cognitive radio
Rojas, Miguel A.; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (2009)
Text en actes de congrés
Accés obertDynamic detection of primary users is one of the main functions of spectrum sensing for Cognitive Radio (CR) communications aiming to increase the use of radio spectrum. In this work the performance of the so-called ... -
Spectrum labeling for cognitive radio systems
Lagunas Hernandez, Miguel A.; Pérez Neira, Ana Isabel; Stoica, Petre; Rojas, Miguel A. (2008)
Text en actes de congrés
Accés obertA key challenge of the air interface of the cognitive radio is an accurate detection of weak signals of licensed users over a wide spectrum range. This paper describes a method for first detecting and next locating in ...
