| description | Multiple-input multiple-output filter bank multicarrier with offset quadrature amplitude modulation (MIMO-FBMC/OQAM) system utilizes the multiple antennas technology, and it can provide more advantages than conventional FBMC/OQAM system. However, due to the inherent imaginary interference, the convention preamble-based channel estimation (CE) methods in MIMO-FBMC/OQAM systems cannot achieve high CE performance and mostly suffer from high peak to average power ratio (PAPR). Motivated by these problems, in this paper, we focus on the efficient preamble design for CE in MIMO-FBMC/OQAM systems. We propose an extended preamble structure which exploits the symmetry pattern to cancel interference and the interference weights in the symmetric structure is taken into account. Since the preamble length is extended, the additional interference effect from the middle of the preamble structure is also considered. The simulation results demonstrate that the proposed preamble method has low PAPR, better bit error ratio (BER), and better mean square error (MSE) performance compared to the conventional preamble methods. |
