摘要：

This paper proposes a Dempster-Shafer theory (DST)-based iterative detection-decoding scheme in multiple-input multiple-output (MIMO) systems. On the one hand, the detection algorithm takes advantage of the characteristics of DST processing uncertainty, improving detection performance. On the other hand, during iterations the detection scheme allows for the soft information outputs from the decoder when combining multiple soft information sources, leading to the performance improvement. Moreover, compared with a related DST-based iterative detection scheme, the proposed algorithm has lower complexity, and its detection performance is closer to that of the optimal detection approach. Simulation results demonstrate the validity of the proposed scheme.
