The importance of fractional bandwidth in ultra-wideband pulse design

摘要: Ultra-wideband (UWB) communications systems provide extremely high data rates while using low transmit power relative to narrowband systems. Previous research concludes that such have characteristics make them appropriate for high-speed wireless network applications. One of the distinguishing aspects UWB signal is an fractional bandwidth when compared with conventional This paper describes how a large leads lower worst-case fading in presence multipath systems, thereby providing significant advantage low-power Also included are measurements made actual showing magnitude strength variations due interference.
