In this paper, we propose a practical iterative 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 space-time bit-interleaved coded modulation (ST-BICM) scheme by using turbo or convolutional codes. This encoding scheme is highly effective if used in conjunction with receiver employing iterative detection and decoding. At the receiver end, we propose a novel multi-antenna detection scheme, which equalizes the intersymbol interferences (ISI) and soft estimate the transmitted symbols. These symbols are then input to a sub-optimal turbo-like receiver that performs iterative decoding of the ST-BICM codes in an iterative and, most important, simple fashion. The simulation results show that the proposed so called Turbo-MIMO transceiver error performance improves with the number of iterations of the decoding algorithm. This performance improvement will enhance the capacity and quality of the wireless link.
