| Resumo |
We focus on full-rate, fast-decodable space–time block codes (STBCs) for 2 x 2 and 4 x 2 multiple-input multiple-output (MIMO) transmission. We first derive conditions and design criteria for reduced-complexity maximum-likelihood (ML) decodable 2 x 2 STBCs, and we apply them to two families of codes that were recently discovered. Next, we derive a novel reduced-complexity 4 x 2 STBC, and show that it outperforms all previously known codes with certain constellations. This work was supported by the STREP project No. IST-026905 (MASCOT) within the Sixth Framework Programme of the European Commission. The work of E. Biglieri was also supported by Sequans Communications, Paris, France. |
