Time synchronization is a major challenge and a rich area of study in ultra-wideband (UWB) communication systems. Transmitted-reference (TR) receivers avoid the stringent synchronization requirements that exist in conventional pulse detection schemes. However, the performance of such receivers is highly sensitive to precise timing acquisition and tracking of integration window that defines the limits of the finite integrator prior to final decision block. In this paper we propose a novel rapid synchronization technique that allows us to extract the timing information very accurately in UWB-TR receivers in the presence of a variety of channel noise and interference. The principles of the method are presented and the BER performance of a synchronized UWB-TR receiver is investigated in the presence of a range of values for timing jitter by computer simulations. Our studies show that the proposed synchronization technique greatly improves the performance of UWB-TR receivers in the presence of jitter and AWGN with modest increase in complexity.
