Abstract
A UWB receiver with time drift correction. After a frequency translation by a quadrature demodulator, a pulsed UWB signal received is integrated on successive time windows, and then sampled. A phase shift estimator determines a phase difference between samples separated by a multiple of the sampling period approaching the period of the pulses of the signal. A controller deduces from this phase difference a time offset to be applied to integrators to synchronize the receiver on the signal received.
