Abstract
A device and a method for determining the arrival time of a UWB signal including at least one pulse modulated at a carrier frequency. The receiver includes a frequency translation stage for translating the UWB signal to a first intermediate frequency and a second intermediate frequency. In an integration stage, the signals translated to the first intermediate frequency and to the second intermediate frequency are integrated on a time window to give a first integration result and a second integration result respectively. The phase deviation is determined between the first and second integration results and from this phase deviation, the arrival time of the UWB signal is deduced.
