MIMO/OFDM is receiving considerable attention for next generation mobile radio communication systems. These systems require improved throughput performance to users at cell-edges. In the authors' previous study, they introduced an enhancement of MLD (Maximum Likelihood signal Detection) algorithm, in which desired and interference signals are jointly detected, to improve the cell-edge throughput in the downlink of single cell-frequency-reuse MIMO/OFDM cellular systems. In order to achieve higher cell-edge throughput in coded OFDM cellular systems, this paper proposes an iterative signal detection with ICI cancellation based on an enhancement of MAP (Maximum A Posteriori Probability) algorithm in which signal path search space includes not only desired signal space but also interference signal space.
