DOI: 10.1109/tvt.2019.2891744
Abstract: Filter bank multi-carrier based on offset quadrature amplitude modulation (FBMC/OQAM) suffers from inter-symbol interference and inter-subchannel interference in multi-path fading channels. By exploiting the special structures of the FBMC/OQAM signal and the resulting correlation matrix… read more here.
