摘要
UWB以其高速率、高频谱利用率、低成本、低功耗和应用范围广等一系列优点受到业界前所未有的关注。介绍了超宽带无线通信技术的基本概念、信道模型、收发机基本结构以及和其它短距离无线通信技术性能的比较,分析对比UWB的两大技术标准:多频带正交频分复用(MB-OFDM)和直接序列码分多址(DS-CDMA),并对其当前应用和未来发展进行相关论述。
UWB attracts great attention from the academe and the industry because of its super characteristics of higher data rate and availability of frequency spectrum, lower cost and power consumption as well as wider applications. The basic concepts of UWB wireless communication, the channel model and the structure of transceiver are presented, the other short distance wireless communication method is compared. The technology standards of UWB （MB-OFDM and DS-CDMA） are analyzed and compared. Finally the current application and the future development are also discussed.
