With the advent of the 4G broadband wireless communications, the combination of multiple-input multiple-output (MIMO) wireless technology with orthogonal frequency division multiplexing (OFDM) has been recognized as one of the most promising techniques. In particular, coding over space, time and frequency domains provided by MIMO-OFDM enables a much more reliable detection and decoding of the message at the receiver. In this article, we review recent advances and state-of-the-art in space-time coding, space-frequency coding and space-time-frequency coding for MIMO-OFDM systems. We then propose a multiuser space-frequency coding for MIMO-OFDM access channels
