초록
This letter proposes a precise two-way ranging (TWR) protocol toward low traffic for asynchronous UWB positioning networks. The proposed TWR protocol pursuing instantaneous ranging update enables the estimation of clock frequency offset to achieve high ranging accuracy. Theoretical analysis and simulation results verify the performance. © 2010 IEEE.
