N2 - Ultra-Wideband (UWB) networks are expected to support a wide range of communication-intensive, real-time multimedia applications. One of the key issues in UWB networks is optimization of Quality of Service (QoS) parameters. To meet the QoS demands of each UWB user and maximize the overall network throughput, several technical aspects shall be concerned, e.g. physical layer transmission format, multi user access format and routing solution. In this paper, a centralized Ultra-Wideband Impulses Radio (IR-UWB) multi user system which contains one Network Coordinator (NC) is considered. A Successive Maximum Likelihood (SML) receiver is designed and presented. It shows that the novel ML receiver outperforms the rake receiver under the multipath environment. Meanwhile, an Optimal Power Allocation (OPA) under the multi user environment is investigated and compared to Maximum Power Allocation (MPA) mechanisms. Our results show that such OPA can increase the overall network throughput in comparison with MPA.
