Design and Research on FBMC-OQAM Multicarrier Technology for 5G

Abstract

Abstract Aimed at the low frequency utilization of OFDM due to adding cyclic prefix, a FBMC-OQAM system design based on frequency sampling prototype filter is proposed. In this paper, the performance difference between FBMC-OQAM and OFDM is studied by building the system model and the effect of the overlap factor of the prototype filter on the performance of multi-carrier technology in FBMC-OQAM system is also studied. It is verified that the system has high frequency utilization and good out-band suppression ability and it has good application value in 5G system.
