Wireless localization systems based on determination of signal runtime, such as time of arrival and time difference of arrival, are of great importance for a variety of applications. In many cases, synchronization of the clocks of the agent nodes to those of the network nodes (anchors) has to be performed together with the localization. The current paper investigates the fundamental accuracy limits...
Wireless localization systems are of great importance for a variety of modern applications. Recently, cooperation among agents (nodes with unknown positions) becomes attractive in localization networks, especially in the infrastructure-limited scenario. In many cases, synchronization of the agents' clocks to the anchors (nodes with known positions) has to be performed together with the localization...
Wireless localization systems based on determination of signal runtime (TOA/TDOA) are of great importance for a variety of applications. In many cases, synchronization of the clocks of the agent nodes to those of the network nodes (anchors) has to be performed together with the localization. The current paper investigates the fundamental accuracy limits of such a joint localization/synchronization...
Impulse-Radio Ultra Wideband (IR-UWB) is a promising technology for indoor localization due to its robustness against multipath interference. In this paper, to deal with the synchronization requirement among anchors in traditional time-difference-of-arrival (TDOA) localization, which is difficult to achieve, an asynchronous time-difference-of-arrival (TDOA) localization method is proposed. The theoretical...
An energy detection-based impulse radio ultra-wideband (IR-UWB) system is proposed in this study. The related synchronization process is investigated on the pulse and frame level respectively. According to the system structure, an optimal transmission mode is described in a typical indoor environment, which could take the balance in the system reliability and effectivity. Meanwhile, the referenced...
