This paper proposes a complexity reduced iterative soft interference canceller (ISIC) to realize broadband mobile transmission in MIMO/OFDM systems and compares its performance with the V-BLAST technique. In the proposed scheme, we apply a minimum mean square error (MMSE) filter only in the first iteration and utilize a matched filter (MF) in the second and later iterations to reduce computational complexity by suppressing residual interference in the first iteration. Computer simulation results confirm that the proposed ISIC can achieve almost equal performance to the MMSE-based ISIC with multiplications reduced by 85 % and outperforms the V-BLAST receiver by about 2 dB in four transmit and receive antennas systems under exponentially distributed twelve path conditions.
