Generalized Frequency Division Multiplexing in Cognitive Radio

På svenska

Author

Summary, in English

Generalized Frequency Division Multiplexing (GFDM) is a recent multi carrier modulation technique that can provide low out-of-band radiation, which makes it an attractive choice for the PHY layer of cognitive radios operating in fragmented TV white spaces. Primary, incumbent signals can now be protected with a geo-location database query mechanism. Even then, sensing opportunistic users (OU) operating in the same frequency band is important in cognitive radio operations. In this paper, a simulation based study has been performed to compare GFDM matched filter based sensing characteristics with traditional orthogonal frequency division multiplexing (OFDM) sensing receiver operating characteristic (ROC) curves. Sensing with a GFDM based cognitive radio receiver shows better sensing performance.
