Bayesian CRLB for hybrid ToA and DoA based wireless localization with anchor uncertainty
In this paper, we derive the Bayesian Cramér-Rao lower bound for three dimensional hybrid localization using time-of-arrival (ToA) and direction-of-arrival (DoA) types of measurements. Unlike previous works, we include the practical constraint that the anchor position is not known exactly but rather up to some error. The resulting bound can be used for error analysis of such a localization syst...
متن کاملA Markov Model for Dynamic Behavior of ToA-Based Ranging in Indoor Localization
The existence of undetected direct path (UDP) conditions causes occurrence of unexpected large random ranging errors which pose a serious challenge to precise indoor localization using time of arrival (ToA). Therefore, analysis of the behavior of the ranging error is essential for the design of precise ToA-based indoor localization systems. In this paper, we propose a novel analytical framework...
متن کاملIdentification of the Absence of Direct Path in ToA-Based Indoor Localization Systems
Ultra-wideband (UWB) indoor positioning systems based on time of arrival (ToA) techniques are considered to be the high precision alternatives to those employing received signal strength (RSS) or angle of arrival (AoA) due to their superior time-domain resolution. However, the performance of such systems may easily be degraded by the blockage of the direct path (DP) and occurrence of undetected...
متن کاملPerformance Improvement of IMR-Based NLOS Detection in Indoor Ultra Wide-Band TOA Localization
SUMMARY Sensor networks, in which many small terminals are wire-lessly connected, have recently received considerable interest according to the development of wireless technology and electronic circuit. To provide advanced applications and services by the sensor networks, data collection including node location is essential. Hence the location estimation is important and many localization schem...
متن کاملMap-based Indoor People Localization using an Inertial Measurement Unit
In this paper, we propose a new approach to map-based indoor localization for walking people using an Inertial Measurement Unit (IMU). Generally, an office building includes various components such as corridors, rooms, floors, staircases, elevators. We consider the components for personal positioning. We present two mapping methods that are a map representation method and a position compensatio...
