摘　　要：In this paper, we propose an Alamouti coding for filter bank multicarrier （FBMC） with cyclic prefix （CP） for two transmit antennas, which can avoid the imaginary interference problem existing in the conventional FBMC with multi-antenna systems. Instead of performing Alamouti coding on original data symbols, we perform Alamouti coding on pre-processing signal at the transmitter in our proposed scheme. We show that our proposed scheme has fast single-symbol maximum-likelihood （ML） decoding and achieves full spatial diversity. Simulation results show that the proposed scheme can achieve the BER performance of Alamouti coding under both of the flat-fading channel and the frequency-selective channel. Therefore, it is an efficient Alamouti coding scheme for CP-FBMC systems with two transmit antennas.In this paper, we propose an Alamouti coding for filter bank multicarrier （FBMC） with cyclic prefix （CP） for two transmit antennas, which can avoid the imaginary interference problem existing in the conventional FBMC with multi-antenna systems.
