A comparison of linear FBMC and circularly shaped waveforms

This paper presents a comparison of the conventional filter bank multicarrier (FBMC) with the generalized frequency division multiplexing (GFDM) and cyclic FBMC (C-FBMC) that have recently been proposed as waveforms candidates for 5G. We identify situations where FBMC outperforms GFDM/C-FBMC, as well as the cases where GFDM/C-FBMC provide more flexibility than FBMC.
