Abstract
As a rapid timing synchronization technique for ultra-wideband (UWB) communications, the timing with dirty templates (TDT) technique effectively collects the multipath energy even when the channel is unknown [7]. In this paper, we investigate TDT algorithms for digital UWB receivers with low-resolution analog-to-digital converters (ADC). Different from the original TDT in [7] for analog UWB receivers, our digital TDT synchronizers here can avoid the ultra-wideband analog delay elements which are difficult to implement at the IC level. Our analysis and simulations show that the (non)data-aided digital TDT algorithms remain operational even when the ADC resolution is very low.
