In this paper, we consider a multicell MIMO-OFDM TDD system where the emphasis is on the downlink for future data-intensive applications. We propose a MIMO scheme that can effectively combat co-channel interference with only local BS coordination and retain the high peak rate achievable for point-to-point single-cell communications. We describe several different levels of CSI availability at both the transmitter and the receiver that lead to different system architecture choices. The performance of rate-1 SFBC code (Shao et al. (2004)) with channel estimation is investigated via simulation; our results show that with pragmatic channel estimation schemes, multi-cell MIMO-OFDM is a good candidate for future high-rate applications.
