Abstract

This paper investigates the coexistence issue between pulsed ultrawideband (UWB) radio devices and the existing narrow band IEEE802.11a systems by using the time-reversal method. In this study, the time reversal is applied to the pulsed UWB system. Based on the statistical path loss model, we compared the time-reversal UWB transmission scheme with the traditional UWB scheme. The comparing results show that the time reversal is a potential candidate for pulsed UWB radios to coexist with more IEEE802.11a devices at a reduced separation distance while without causing dangerous interference.
