Abstract:This paper proposes a novel receiver scheme for multiple-input multiple-output (MIMO) systems with hybrid automatic-retransmission-request (HARQ) mechanism. The scheme is based upon Dempster-Shafer evidence theory (DST), and improves the decoding performance by characterizing the uncertainty contained in the received signals. In addition, the new scheme can further counteract the uncertainty of the soft decisions by combining multiple soft information sources. Furthermore, it can make full use of the received … Show more
