【摘要】 通过将超宽带(UWB)无线通信技术应用于组建无线个人局域网(PAN)和无线多媒体网络,可实现数据在近距离范围内的高速传输,并有效地解决了信道衰减、成本高和功耗大等难题,同时,UWB技术也可应用于探测、定位、成像等方面。文章通过介绍UWB无线通信技术的基本概念,分析了它的2种调制方式以及性能特点,最后详细介绍了其在无线通信中的应用。更多还原

【Abstract】 The data can be transmitted at a high speed within close quarters by applying the ultra-wideband(UWB) wireless communication technology in the wireless Personal Area Network(PAN) and the wireless multimedia network.The difficult problems have been solved,such as channel decaying,high cost,high power dissipation and so on.Meanwhile,UWB technology can be applied to detecting,orientation and imagining etc.This paper analyzes two kinds of modulation ways of UWB signal and their performance characteristics through introducing the basic conception of UWB wireless communication technology.In the last part of this paper,UWB applications in wireless communication were described in detail.更多还原
