摘要 超宽带(UWB)技术以其在无线通信网络、雷达、图像和定位系统中极具吸引力的特点,而正在成为无线通信的热点技术之一。针对UWB系统中的同步问题,首先介绍了目前主流的三种同步方案,分析了各自的优点和缺点,并由此进一步分析了若干同步研究的方法。最后,指出了UWB同步研究的主要难题,提出未来的研究方向。 Ultra-Wideband(UWB) radio is becoming a hot technology with uniquely attractive features in wireless communications net- working, radar, imaging and positioning systems. The paper firstly introduces three mainstream synchronization schemes and their advantages and disadvantages. Then it analyzes some synchronization research methods. Finally it shows the main dif- ficulties in UWB synchronization research and gives the future research trends.
