摘要：

FBMC/OQAM transmission system has a better spectral efficiency than OFDM. However, its orthogonality condition is only considered in the real field. In the presence of fading channels, the real orthogonality of FBMC/OQAM might be lost, which calls for new equalization schemes. In this paper,an improved equalizer with real interference prediction(ERIP) scheme of FBMC/OQAM is proposed.We analyze the correlation between the real and the neighboring imaginary interference components taking Doppler shifts into account, and derive the improved ERIP scheme. The simulation results show that the proposed scheme can outperform the original ERIP and the one-tap equalization in time-varying multipath scenarios with an affordable complexity.
