Abstract: As a candidate waveform for next-generation wireless communications,generalized frequency division multiplexing (GFDM) features several decentproperties which make it promising. In this paper, we systematically overviewthe research about GFDM. We start with GFDM transceivers with their maincomponents, which consist of prototype filter design, low-complexitytransceiver implementation, and symbol detection algorithms. Then, weinvestigate a couple of non-ideal issues of GFDM, including synchronizationissues, channel estimation, and in-phase quadrature (I Q) imbalancecompensation. Lastly, we study the applications of GFDM-based cognitive radioand full-duplex radio which boast of a high spectral efficiency.
