Abstract
A method for determining arrival time of a UWB pulse at a receiver. When a pulse is modulated at an RF frequency, the receiver includes a quadrature demodulator, a first correlating stage for correlating the in-phase signal with the first and second signals of an orthogonal base on a time window and a second correlating stage for correlating the quadrature signal with the first and second signals of the orthogonal base on the same window, a phase estimator estimating the phase of the signal received in the orthogonal base from the correlation results of the first and/or second correlating stage(s), and a computing device determining the arrival time from the phase thus estimated.
