In this paper, we introduce a family of full-diversity space-frequency codes (SFCs) for the multi-input-multi-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems. The most important feature of the proposed SFCs is that they can be swiftly decoded. More precisely, the decoding complexity on the order of O (M) or O(M-2) can be attained for the proposed full-diversity SFCs, where M is the constellation size. Simulation results have also verified that the proposed SFCs display outstanding performance in comparison with the latest SFC model published in the literature.
