Ultra wide band system performance with a new timing acquisition approach

In the last years, Ultra Wideband (UWB) systems have received growing interest for their low-power consumption and low-complexity implementation. Because of the ultra-short emitted waveforms nature, timing acquisition presents a most important challenge for achieving good performance. In this paper, in order to address this task and to achieve this goal, we design and test a novel timing acquisition approach based on two-stage scheme. In fact, our synchronization arrangement is composed of a blind synchronization that is Timing with Dirty Templates (TDT), followed through a new fine synchronization algorithm developed in [1-5] which will result to a well improved performance. Analysis and simulation results confirm performance improvement of our timing acquisition approach relative to the original TDT in terms of bit error rate (BER) and mean square error (MSE). Our approach can even offer a BER performance close to that corresponding to the case with perfect timing.
