In coded multiuser tracking and data relay satellite system (TDRSS) return link, multiple access interference and inter-symbol interference are major impediment to reliable communication. While the optimal soft-input soft-output multiuser detection scheme results in a prohibitive computational complexity. In this paper, a simplified hard-input soft-output (HISO) scheme for low-density parity-check...
In this paper, the decision-level data fusion techniques are extended to the multiuser detection (MUD) field. Then a novel MUD algorithm that is the combine application decision-level fusion criterion (CA-DFC) based MUD algorithm is proposed for DS-UWB communication systems. In CA-DFC based method, the combine detectors can make decisions among the preliminary decisions from sub-optimal detectors...
