Abstract :
In mobile reception of OFDM, reception characteristics are deteriorated by inter-carrier interference (ICI). ICI is occurs caused by Doppler-spread. The ICI canceller with complexity reduction scheme has already been proposed. The reception characteristics of ICI canceller with complexity reduction scheme are deteriorated than ordinary ICI canceller. In this paper, the improving scheme of ICI canceller with low complexity is proposed. The proposed scheme adopt iterative detection using provisional demodulated symbols. As the results of simulation, the proposed scheme can improve reception characteristics.
