Abstract :
In MIMO(Multiple-Input Multiple Output)-OFDM(Orthogonal Frequency Division Multiplexing) systems, ICI(Inter-Carrier Interference) is generated by Doppler-spread in mobile reception of OFDM signals. The MIMO-ICI canceller with complexity reduction has been proposed. It is possible to reduce the complex. However, reception characteristics are deteriorated than the ordinary MIMO-ICI canceller. In this paper, the improving scheme of the conventional MIMO-ICI canceller with complexity reduction is proposed. In the proposed scheme, the iterative detection is adopted. As the results of computer simulations, the proposed scheme can improve reception characteristics with complexity reduction.
