TL;DRAbstract
Since the discovery of the significant gain in capacity provided by multiple antennas over fading channels, tremendous research and development efforts in academia and industry have been invested to multiple-input-multiple-output (MIMO) technology. However, difficulties still exist in the design of flexible MIMO transmission schemes. The overall goal of our study is to develop efficient turbo MIMO transceivers that are capacity-achieving and yet with reasonable complexity. First, we study the design of serially concatenated MIMO transmitters. For simpler design and flexible rate-versus-performance tradeoff, conventional encoders are used before a linear space-time modulator. A joint iterative receiver based on the turbo principle is assumed that precludes the use of Tarokh's design criteria for such a concatenated system. Extending the extrinsic information transfer (EXIT) charts to MIMO systems, design criteria that concern both the data rate and error performance are developed for th
