摘要：

To synchronize Ultra-Wideband (UWB) signals with pulse amplitude modulation (PAM) and time hopping (TH) spreading in ad-hoc multi-user environments, we propose in this paper to develop and test a novel fine synchronization algorithm in both data-aided (DA) and non-data-aided (NDA) modes. The proposed synchronization scheme is decomposed into two successive floors or steps. The first floor consists on a coarse synchronization which is based on timing with dirty templates (TDT) acquisition scheme. In the second floor, we consider a new fine algorithm which provides an ameliorated estimate of timing offset. Simulation results and comparisons are also presented to confirm our theoretical analysis and performance improvement (in terms of mean square error) compared to the original TDT algorithm in multi-user environments.
