The deployment of RFID technology will gain a significant boost if indoor location positioning is incorporated into RFID systems. Recent development in range estimation indicates that phase difference of arrival (PDOA) shows a promising performance. PDOA technique suffers from an inherited limitation of phase difference which is restricted to the maximum of 2π radians. In this paper a robust algorithm to overcome this limitation and unwrap the phase is presented. A theoretical model has been developed to accurately unwrap the phase using the round trip time of flight. Simulation results show that the proposed method can be used to estimate the range even under significant Round Trip Time of Flight (RTTF) measurement error. It is shown that a wide range of time measurement errors can converge to actual distance if the frequency difference of the transmitted waves is properly selected.

“…It proposes a simple architecture that extends the state of the art in this field [14] by experimentally proving that accurate positioning can be achieved by avoiding the need for complex and expensive solutions. In fact, recently published positioning methods rely on the synchronization of anchors or on the usage of hybrid direction-of-arrival/timeof-arrival approaches or on the usage of complex high-speed correlators and digital processing, as published in [15]- [18]. At the same time, because of the adopted measurement method and of the chosen frequency band, bulky antenna arrays as those used in [19] may be avoided.…”

This paper describes the design and realization of a 5.6-GHz ultrawide-bandwidth-based position measurement system. The system was entirely made using off-the-shelf components and achieves centimeter-level accuracy in an indoor environment. It is based on asynchronous modulated pulse round-trip time measurements. Both system level and realization details are described along with experimental results including estimates of measurement uncertainties.Index Terms-Instrumentation and measurement, radio navigation, radio transceivers, signal processing algorithms, ultra wideband technology.

An asynchronous time difference of arrival (ATDOA) positioning system requires no time synchronization among all the anchor and target nodes, which makes it highly practical and can be easily deployed. This paper first presents an ATDOA localization model, and then primarily focuses on two new localization algorithms for the system. The first algorithm is a two-step positioning algorithm that combines semidefinite programming (SDP) with a Taylor series method to achieve global convergence as well as superior estimation accuracy, and the second algorithm is a constrained least-squares method that has the advantage of low complexity and fast convergence while maintaining good performance. In addition, a novel receiver re-selection method is presented to significantly improve estimation accuracy. In this paper, we also derive the Cramer-Rao lower bound (CRLB) of the ATDOA positioning system using a distance-dependent noise variance model, which describes a realistic indoor propagation channel.
