Abstract
A robust time shift tracking UWB receiver. After translating in baseband by a quadrature demodulator, the received UWB pulsed signal is integrated on successive time windows, and then sampled. The complex samples are then correlated with a coding sequence from the transmitter and then transmitted on the one hand to a phase estimator and a demodulating/detecting module. The latter estimates the symbol emitted and provides it to the estimator which removes the modulation effect for estimating, at each time-symbol, the phase of the complex samples. A phase rotation follow-up module determines a compensated phase rotation and a non-compensated phase rotation from a reference instant. Controlling means deduce from the non-compensated phase rotation a time offset to be applied to the integration windows.
