In this paper, with the advent of next generation (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 to support high data rate and high performance. In particular, coding over the space, time, and frequency domains provided by MIMO-OFDM will enable a much more reliable and robust transmission over the harsh wireless environment. In this paper, the authors provide an overview of Space-Time (ST) coding, Space-Frequency (SF) coding, and Space-Time-Frequency (STF) coding for MIMOOFDM systems.
