Abstract
High-accuracy and low-complexity ranging is essential to a number of wireless applications, especially wireless localization networks. Since ultra-wideband (UWB) signals can realize accurate ranging even in harsh environments, we design and implement an experimental low-complexity noncoherent UWB ranging system. This system adopts two-way time-of-arrival (TW-ToA) ranging protocol and uses the time-to-digital-converter (TDC) to measure time difference between the transmission and the reception of ranging frames. Preliminary experimental results show that this system can achieve sub-meter ranging accuracy.
