摘要

Filter-bank multicarrier(FBMC) with offset quadrature amplitude modulation(OQAM) is a candidate waveform for future wireless communications due to its advantages over orthogonal frequency division multiplexing(OFDM) systems. However, because of orthogonality in real field and the presence of imaginary intrinsic interference, channel estimation in FBMC is not as straightforward as OFDM systems especially in multiple antenna scenarios. In this paper, we propose a channel estimation method which employs intrinsic interference cancellation at the transmitter side. The simulation results show that this method has less pilot overhead,less peak to average power ratio(PAPR), better bit error rate(BER), and better mean square error(MSE) performance compared to the well-known intrinsic approximation methods(IAM).
