Abstract

Based on the existing IR-UWB indoor-positioning receiving system[1], a novel charge-pump PLL receiving system with AGC is proposed to accurately estimate UWB pulse arrival time, and achieve the goal of accurate indoor ranging and positioning. Pulse rising-edge detection APulse-broadening circuit is mainly discussed, and some new phenomena are analyzed, which can be used for narrow pulse detection. Results show that the novel scheme has strong reliability, high positioning accuracy and simple circuit implementation.
