摘　　要：在高速移动专用ad hoc网络中,考虑节点通信负荷、速率等要求,无线信号传输的特点以及UWB信号的自身特征,对处于二维平面内节点间通信链路进行了建模,并在此基础上进行了仿真。本文重点在由节点间相互运动差导致的不同Doppler扩展下对三种不同接收机的性能及其变化趋势进行了研究与分析。最后,提出了以后进一步的研究方向和内容。In high speed mobile specialized ad hoc network,considering these requirements,such as commu--nication loads and rates between nodes,characteristics of wireless signal transmission and the characteristics of UWB signal etc.,the communication chain among the nodes in the two-dimentional level has been modeled and emulated. The performances of three different kinds of receivers and variation tendency under different Doppler spreads,which caused by the difference of moving among nodes,have been especially stud...
