This paper is concerned with coded multiple-input multiple- output orthogonal frequency division multiplexing system with index modulation (MIMO-OFDM-IM) for high mobility wireless communications. To improve the bit-error rate (BER) performance, the block Markov superposition transmission (BMST) codes are constructed and combined with MIMO-OFDM-IM, where a genie-aided lower bound is also presented to predict the performance of the BMST- MIMO-OFDM-IM in the low-BER region. At the receiver, submatrix based linear minimum mean square error (LMMSE) equalization is employed in conjunction with the soft demapping algorithm. Simulation results demonstrate that the BMST-MIMO-OFDM-IM can achieve significant coding gain compared with BMST-MIMO-OFDM over doubly selective channels.
