In MIMO-OFDM systems, the time-varying fading of channel can destroy orthogonality subcarriers. This causes serious intercarrier interference (ICI), thus leading to significant system performance degradation, which becomes more severe as normalized Doppler frequency increases. this paper, we propose a low-complexity iterative receiver with joint frequency-domain ICI cancellation and pilot-assisted estimation minimize effect channel. At first stage receiver, between adjacent sub-carriers is...
