Abstract

Massive MIMO and filtered multi-carrier waveforms are considered as key enabling technologies for next-generation wireless networks. In this work, the Filter Bank Multi-Carrier (FBMC) waveform solution applying our previously proposed short filter and advanced receivers is extended to massive MIMO systems and evaluated in comparison to OFDM. Simulation results are presented for the non-line of sight (NLOS) 3D Urban-Macrocell (UMa) model of the 5G QuaDRiGa channel. Results show that the solution applying the proposed Overlap-Save (OS) and Overlap-Save-Block FBMC (OSB) receivers outperforms OFDM under timing offsets, carrier frequency offsets and Doppler spreads. Moreover, they confirm that the Overlap-Save FBMC receiver can support asynchronous communications in the context of massive MIMO, a cornerstone for grant-free communications and massive access.
