摘要
超宽带(UWB)脉冲无线电(IR)技术是一个新兴的通信技术,具有诸多的优点,正受到人们越来越广泛的关注。Simulink是一种用来建模、仿真和分析动态系统的集成仿真工具。该文介绍了超宽带脉冲无线电和Simulink的特点,在Simulink环境下搭建并实现了超宽带通信系统的仿真。提出了在跳时(TH)脉冲位置调制(PPM)通信系统中的同步相关算法,主要对仿真链路中的接收机进行设计和实现,其中包括信号检测、伪随机序列捕获、数据同步等。结果表明,该仿真系统在超宽带通信中是可行的。
<Abstrcat>Ultra Wide-band Impulse Radio is a novel communication technology. It has many advantages and is being concerned widely. Simulink is an interactive tool for modeling, simulating, and analyzing dynamic systems. This paper introduces the characteristics of ultra wide-band impulse radio and the Simulink , constructs and implements the simulation model of UWB communication systems in Simulink. And it presents the synchronization-correlation algorithm in TH PPM communication systems, including UWB signal detection, PN sequences acquisition, and data synchronization. The simulation results show that the proposed model is feasible in UWB communication systems.
