Turbo-like MIMO systems with and without space-time codes

We analyze MIMO systems where either Bit-Interleaved Coded Modulation (BICM) by itself or in concatenation with Space-Time Block Codes (STBCs) is used at transmission, assuming iterative Turbo-like decoding at reception. We employ Serially-Concatenated Low-Density Generator Matrix (SCLDGM) codes specifically optimized for each system configuration, and focus on two relevant STBCs: the Golden code, which provides a capacity increase, and Linear Dispersion (LD) codes, which enable practical detection in asymmetrical antenna configurations (i.e., more transmit than receive antennas) for cases in which optimum detection is infeasible.
