Zhang, Peng; Joiner, Laurie L. STF coding for MIMO-OFDM systems with four or three transmit antennas. (English) Zbl 1107.94014 Int. J. Pure Appl. Math. 29, No. 3, 405-413 (2006). Summary: A space-time-frequency (STF) coding scheme based on quasi-orthogonal space-time block coding (QOSTBC) for MIMO-OFDM systems with four or three transmit antennas is presented. A low-complexity linear decoding algorithm is develops to mitigate the diversity loss caused by inter-symbol couplings in decoding of the block code in a non-quasi-static OFDM channel. Simulation shows that the proposed coding scheme combined with the linear decoder exhibits a significant advantage in BER performance and decoding simplicity over the counterpart space-frequency (SF) scheme in a slow fading channel.
