| 摘要: |
| 超宽带系统通常使用纳秒级的超宽带脉冲，系统内所有用户实现同步是非常困难的。本文提出了一种时分多路复用(TDM)网型超宽带系统，根据系统内同步基准站提供的同步信息和每个用户分配的发送时间，实现系统内所有用户间信息交换。计算机仿真和理论计算结果表明：同步帧中使用的同步脉冲越多，同步概率越高。 |

| () |
| Abstract: |
| An Ultra-Wide Bandwidth (UWB) system usually operates by using impulse on the order of a nanosecond. It is very difficult to synchronize among the system users. Based on the Time-Division Multiplexing (TDM) protocol, this paper presents a net-like UWB system. With the help of synchronization provided by the synchronization station, each user transmits data to other users at the assigned time. Simulation results and theoretical analysis indicate that the more synchronization impulses are used in one synchronization frame, the higher the synchronization probability. |
