In this paper, we propose a practical transceiver design for multiple-input, multiple-output (MIMO) frequency-selective wireless channels, which is able to realize a significant portion of the capacity promised by information theory. At the transmitter end, we exploit the idea of the random layered space-time (RLST) coding scheme by using independent block codes and random space-time interleaving. At the receiver end, we propose a novel multi-antenna detection scheme, which equalizes the intersymbol interferences and estimate the (soft) transmitted symbols. These soft estimated symbols are then input to a sub-optimal turbo-like receiver that performs iterative decoding of the RLST codes in an iterative and, most important, simple fashion. The simulation results show that the proposed Turbo-MIMO transceiver error performance improves with the number of iterations of the decoding algorithm.
