Abstract(in English) | A turbo-coded MIMO-SDM system requires a soft-output MIMO detector. Although MAP-based soft-output detection is optimum, its hardware implementation is very difficult since its computational complexity increases exponentially with the antennas and constellations. Sphere decoding (SD) is one of promising ways to reduce the computational complexity effectively. In SD, however, it occasionally excludes signal points required for the likelihood estimation in turbo decoding. In this paper, we propose a method recovering the signal points outside the sphere, and its error performance is evaluated. The simulation results reveal its extremely low complexity. |
