| description | In the upcoming fifth-generation (5G) mobile network, the filter bank multi-carrier (FBMC) technique provides an alternative to cyclic prefix-orthogonal frequency-division multiplexing (CP-OFDM). The most fascinating features of FBMC are high spectral efficiency and extremely low out-of-band emissions by removing the CP and using well-localized pulse shapes. FBMC exhibits intrinsic inter-carrier/intersymbol interference which can be mitigated by techniques such as offset quadrature amplitude modulation (OQAM). However, OQAM does not work well in multi-path fading channels. Consequently, conventional channel estimation methods and MIMO based upon space-time/frequency block coding are not straightforward applicable to the FBMC system. This paper presents two new transceiver architectures for the FBMC/QAM matrix. First of all, the matrix models of the FBMC/QAM scheme are derived. Second, based on the matrix models, three receiver methods are then described. Then, the scheme of combining FBMC/QAM with channel estimation and MIMO is proposed. Finally, two simplified receiver algorithms based on the matrix models are proposed. Simulation results indicate that the proposed transceivers of the FBMC/QAM matrix scheme can directly combine with the channel estimation and MIMO techniques used in conventional OFDM systems. Furthermore, the proposed transceivers of the FBMC/QAM matrix scheme have almost the same BER performance compared with the conventional OFDM systems. |
