Abstract
Synchronization performance of a pulse-based ultra- wideband (UWB) system is investigated by taking into account of distortions caused by transmitter and receiver antennas and wireless propagation channels in difierent environments. The synchronization scheme under consideration can be achieved in two steps: a slide correlator and a phase-locked loop (PLL)-like flne tuning loop. Efiects of the non-idealities are evaluated by analyzing the distortion of the received UWB pulse and subsequently the synchronization performance of the pulse-based UWB system. It is found that generally a smaller step is required for the sliding correlator due to distortions introduced by the antennas and channels. However, the flne tuning loop can always be stabilized by adjusting the loop parameters. Therefore, synchronization can always be achieved.
