N2 - This paper proposes an irregular code-aided iteratively detected three-stage space-time scheme for a MIMO system. Benefiting from the serial concatenation at the transmitter of a space-time mapper, a low complexity unit rate code and an outer irregular code, and iterative processing among the three constituent detector/decoder at the receiver, the resultant system is capable of achieving error free transmission for a sufficiently long interleaver block, and the overall rate is close to the space-time detector constrained maximum achievable rate. The space-time detector of our system employs either multi-feedback serial interference cancelation (MFSIC) aided soft-output parallel interference cancelation (SOPIC) which can effectively reduce the required iterations to achieve full iteration gain or soft-output complex sphere decoding (SOCSD) which is capable of operating within 0.4dB away from the ergodic MIMO channel capacity.
