We present a space-time coded system which achieves high throughput and good performance using low- complexity detection and decoding. We focus on a Rate 2 quasi- orthogonal space-time block code structure which enables us to achieve an overall throughput of 5.6 bits/symbol period with good performance and relatively simple decoding using iterative parallel interference cancellation. We show that this can be achieved through the use of a bit-mapped coded modulation (BMCM) structure using parallel short low density parity check codes. The proposed system is shown to perform well on flat Rayleigh fading channels with a wide range of normalized fade rates, and to be robust to channel estimation errors. A comparison with bit-interleaved coded modulation (BICM) is also provided.
