In this paper, to synchronize Ultra WideBand (UWB) systems in ad-hoc multi-user environments, the authors propose a new timing acquisition approach for achieving a good performance despite the difficulties to get there. Synchronization constraints are caused by the ultra-short emitted waveforms nature of UWB signals. Used for single-user environments, their timing acquisition approach is based on two successive stages or floors. Extended for multi-user environments, the used algorithm is a combination between coarse synchronization based on Timing with Dirty Templates (TDT) acquisition scheme and a new fine synchronization scheme developed which conduct to an improved estimate of timing offset.
