Since very short pulse waves are transmitted, UWB systems have excellent accuracy in terms of distance measurement. In order to measure the distance between the terminals, the transmitted pulses have to be synchronized by a delay-lock-loop (DLL) in the receiver. In this paper the performance of the DLL is evaluated. Its performance depends the timing jitter between the local clocks of the terminals.
