Abstract	In MIMO-OFDM systems, the time-varying fading of channel can destroy the orthogonality of subcarriers. This causes serious intercarrier interference (ICI), thus leading to significant system performance degradation, which becomes more severe as the normalized Doppler frequency increases. In this paper, we propose an effective scheme to eliminate ICI for space-time trellis-coded (STTC) systems. By restricting the interference to the limited number of neighboring subcarriers, the computational complexity of our proposed receiver can be significantly reduced. Simulation results show that the proposed MIMO-OFDM receiver can effectively mitigate the effect of ICI and approach the ICI-free performance over time-varying frequency-selective fading channels.
