Timing synchronization and tracking represent major challenges in carrying out highly efficient ultra-wideband (UWB) communications. The Delay-Locked Loop (DLL) method is widely proposed to maintain satisfactory synchronization. In this paper, we suggest a novel DLL structure design for UWB systems based on an approach called Timing with Dirty Template. This approach promises to improve tracking performance while maintaining low-complexity structure. The parameters of the proposed DLL will be selected to optimize tracking behavior in the presence of the ambient noise and Doppler effects. Simulation results show tracking performance across various DLL parameter values
