Recent research has shown that the performance of multiple antenna systems, often referred to as multiple-input multiple-output (MIMO) systems, can be significantly improved by using the principle of iterative, or "turbo" processing. The resulting class of MIMO systems is referred to as Turbo-MIMO. This chapter discusses a Turbo-MIMO architecture based on space-time bitinterleaved coded modulation (ST-BICM), which is highly effective if used in conjunction with receivers employing iterative detection and decoding. It reviews three recent low-complexity detection schemes that can be used in such systems, i.e., minimum mean-squared based soft-interference cancellation soft-interference cancellation (SIC-MMSE), iterative tree search (ITS) detection, and list sphere detection. Simulation results are presented which show that, with the aid of these or similar schemes, the embodiment of the turbo processing principle with MIMO architectures provides a practical solution to the requirement of high data-rate transmission in a reliable manner for future wireless communication.
