Abstract(in English) | Generalized Frequency Division Multiplexing (GFDM) with its flexible pulse shaping filters can provide extremely low out of band leakage to adjacent legacy channels. This makes it an attractive choice for a PHY layer of cognitive radios operating in fragmented TV white spaces. Introducing zero padding to the transmission data block significantly reduces the said out of band leakage even further. Primary, incumbent signals can now be protected with a geo-location database query mechanism. Even then, sensing opportunistic users 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. If we incorporate the improved lower ACLR pulse, then the sensing characteristic curves become even better. |
