超宽带（UWB）无线通信技术研究

摘要

UWB (UltraWideband), namely ultra wideband. Short distance wireless communication technology which originated in nineteenth Century. UWB has a strong anti-jamming capability, high transmission rate, wide bandwidth, small power consumption, small transmission power, good secrecy, has the advantages of small radiation on the human body, in the ifeld of WPAN has become one of the most competitive technology. This paper mainly discusses the development and application of UWB, and make a prediction of future development.%UWB（UltraWideband），即超宽带。一种起源于19世纪的无线短距离通信技术。UWB具有抗干扰性能强、传输速率高、带宽极宽、消耗电能小、发送功率小、保密性好、对人体辐射小等优点，在无线个域网领域中已成为最富有竞争力的技术之一。文章主要论述UWB的发展现状及应用，并且对未来的发展作出预测。
