- Abstract
- This paper introduces an efficient multiple-decision-feedback (MDF) detection for space time block code (STBC) over time-selective fading channels. The MDF detection performs several decision-feedback (DF) detections for the most probable points obtained by a log-likelihood ratio (LLR) based bit flipping scheme. Simulation results show that, with reasonable complexity, the MDF detection provides near maximum likelihood (ML) performance by achieving the considerable SNR gain, compared with the existing DF detections. © 2009 IEEE.
