Demands for indoor positioning based services (IPS) in commercial and military fields have
spurred many positioning systems and techniques. Complex electromagnetic environments …

Many emerging applications, such as security surveillance and smart healthcare, have
incubated the device-free localization (DFL) technique, which could estimate the location of …

Near-field (NF) localization is a key research topic in various applications, including
autonomous vehicles, real-time tracking, target monitoring, etc. However, the traditional NF …

In this letter, we address the moving source localization problem by using time-difference-of-
arrival and frequency-difference-of-arrival measurements. The localization problem is first …

This paper develops two convex relaxation solutions for the unified localization of a signal
source using time difference of arrival measurements, regardless of whether the source is in …

Localization is perhaps one of the most interesting research subjects in signal processing.
Traditional localization methods rely on the prior information whether the source is located in …

In most existing localization schemes, location information leakage is inevitable, since both
the locations of the target and the anchors will be revealed to the entity that conducts …

Multidimensional scaling (MDS) is an attractive method for location-related applications due
to its robustness against noise. This paper applies MDS to time difference of arrival (TDOA) …

This paper considers the problem of locating a target in 2D from range measurements
containing outliers. Assuming the number of outliers is known, we formulate the problem of …

Small and pervasive devices have been increasingly used to identify and track objects
automatically. Consequently, several low-cost localization schemes have been proposed in …
