Automatic signal recognition for a flexible spectrum managment

By Niclas Björsell, Pasquale Daponte, Luca De Vito and Sergio Rapuano


Abstract − The paper presents the prototype of an automatic digital modulation classifier, to be used for signal recognition in frequency bands managed in a flexible way. The prototype is based on a Data Acquisition System, consisting of an Analog-to-Digital converter embedded in an evaluation board, a frame grabber and a Personal Computer. The modulation classifier is able to recognize the most used digital modulations. An experimental validation of the realized prototype in a radio environment is also provided
