摘要

本文研究了直接序列超宽带(DS-UWB)和超宽带调频(UWB- fm)两种单波段超宽带(UWB)系统在两种不同信道模型下的性能，揭示了信道模型对系统性能的影响。应用的信道模型是芬兰无线通信中心(CWC)开发的实验性无线体域网络(WBAN)信道模型和IEEE 802.15.6信道模型。仿真结果表明，WBAN信道模型的选择对UWB-FM的性能有重要影响，而DS-UWB信道模型的选择对UWB-FM性能影响不大。

Impact of difference in WBAN channel models on UWB system performance

In this paper, the performances of two singleband ultra wideband (UWB) systems, i.e., direct sequence UWB (DS-UWB) and UWB frequency modulation (UWB-FM) are studied in two different channel models to reveal an impact of a channel model on the system's performance. The applied channel models are the experimental wireless body area network (WBAN) channel model developed at the Centre for Wireless Communications (CWC), Finland, and the IEEE 802.15.6 channel model. The simulation results indicate that the choice of the WBAN channel model applied in the simulations has a major impact on the performance of UWB-FM, whereas it is not such a crucial in the case of DS-UWB.
