摘要/Abstract

摘要：

提出了一种超宽带同步的新方法，即在2个相互正交的波形上，分别调制同步头和数据信号后，将其合成为发送信号进行传输，接收端利用正交波形进行滤波分解，得到所传送的同步头和数据信号. 在此基础上，设计出基于这种新的同步方法的信息传输系统，分析了影响同步性能的因素，并对整个系统进行仿真验证. 仿真结果表明，该系统可以同时传送同步头和数据信号，并可显著提高同步性能.

Abstract:

A new ultra wideband (UWB) synchronization method is presented. This method modulates the synchronization signals and information signals respectively on tow carrier waves which are orthogonal mutually, and then combines them to transmit. After the hybrid signal is received, it will be decomposed according to the characteristic of orthogonal waves to get the synchronization signals and information signals. The information transmission system is designed by using this synchronization method. We also simulate the system and analyze the performance. The result of the simulation indicates that the system uses this synchronization method can transmit the synchronization signals and information signals at the same time and improve the synchronization performance obviously.

Key words: radio-communication, ultra wideband, orthogonal waves, synchronization
