从超宽带(UWB)无线技术产生的背景出发,概括了UWB系统的特点,讨论了UWB的应用前景;同时指出,UWB利用的是频谱重叠技术,频带非常之宽,有许多课题有待于去解决;最后提出了一种UWB抗干扰系统的实现方案。
Abstract：With the existence of the ultra wide band technology,the characteristics of the UWB wireless technology are summed up and the potential applications are discussed.As the UWB uses the overlapping spectrumand the band is very wide,there are a lot of problems waiting to be solved.Finally,the UWB-OFDMsystemwith robustness to interference is proposed in this paˉper?
