| 摘 要： | 超宽带是通信领域的新技术,使用纳秒级短脉冲承载信息,其同步一直是研究的热点。针对超宽带系统对同步要求高度准确的特点,结合现有同步方法,借助信道辨识,使用非相干超宽带系统,提出了一种更有效的同步方法。在标准的IEEE802.15.4a信道环境下,通过信道辨识,对脉冲展宽与同步性能的关系进行了探讨。最后的仿真实验表明,该方法是一种有效的同步方法。

| Abstract: | Ultra-Wide Band（UWB） is a new and emerging technology in communication area,which carries information by the nano-level short pulses,and its synchronization is always a research focus.For the requirement of fast and accurate synchronization by UWB system,a new effective synchronization method is proposed.To be elegant,the non-coherent UWB system is adopted,and to be effective,the channel identification is combined.In the environment of IEEE 802.15.4a channel,with the help of channel identification,the relationship of pulse widening and synchronization performance is explored.The simulation results indicate that the synchronization method proposed in this paper is feasible and effective in practice. |
