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. |
