To improve bit error rate (BER) and data rate performance in filter bank multicarrier-quadrature amplitude modulation (FBMC/QAM)-based evolved multimedia broadcast multicast system (eMBMS), effective channel estimation using iterative interference cancellation has been introduced in literature. This research mainly has been based on single-input single-output FBMC/QAM-based eMBMS. In contrast, in multiple-input single-output (MISO) FBMC/QAM-based eMBMS, there exists a residual interference from other antennas, and the influence of it on channel estimation for multiple antennas remains still unverified. In this paper, we derive the residual interference in MISO-FBMC/QAM-based eMBMS in order to analyze and clarify the influence of the residual interference on channel estimation. In addition, we propose new reference symbol (RS) structures for the 2 × 1 and 4 × 1 MISO-FBMC/QAM-based eMBMSs that are more robust against the residual interference. Finally, we propose a cross-antenna interference cancellation -based channel estimation method to eliminate the residual interference and improve the channel estimation accuracy. The simulation results show that the proposed RS structures and channel estimation method improve the mean squared error, BER, and effective data rate.
