N2 - 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 by a special rule. Simulation results demonstrate that the performances of CA-DFC based MUD algorithms are superior to those of other sub-optimal MUD algorithms, and even close to that of OMD. Moreover, the proposed algorithm have lower computational complexity than OMD, which reveals their efficiency. Compared with CA-DFC based algorithm achieves a little improvement in its performance, at the cost of the increment in its computational complexity. Thus, they can be applied to different practical situations.
