【摘要】 目前电力线载波通信面临着传输速率、可靠性及电磁兼容等诸多方面的挑战。近年来,迅猛发展的超宽带无线通信技术为应对这些挑战提供了新的思路。文章首先简要介绍了超宽带通信技术,在分析低压电力线信道特性的基础上,用SystemV iew软件建立超宽带脉冲通信系统模型,并进行了原理性仿真;探讨将超宽带技术(UWB)应用于电力线高速通信的可行性,并就其中的关键和难点进行了归纳和阐述;最后展望了应用前景。更多还原

【Abstract】 At present,Power Line Communication(PLC) faces many challenges,such as the transfer rate,reliability,and electromagnetic compatibility etc.The Ultra-Wide Band(UWB) wireless communication technology has been developing rapidly in recent years,and it offered a new thinking to reply these challenges.The article introduces UWB technology briefly at first;and then on the basis of analyzing channel characteristic of the low-voltage power line,the systematic model of UWB pulse communication was set up with System View software,and the simulation results are given.The feasibility of ultra-wild band technology applying in high-speed power line communication is discussed,and furthermore some key issues in practice are presented.Finally,the prospect of UWB applied to power line communication is brought forward.更多还原
