Terahertz (THz) communications are celebrated as key enablers for converged localization
and sensing in future sixth-generation (6G) wireless communication systems and beyond. …

This paper presents a novel reference-free ultrasonic indoor location system. Unlike most
previous proposals, the mobile device (MD) determines its own position based only on …

Reconfigurable intelligent surface (RIS)-assisted localization has attracted extensive attention
as it can enable and enhance localization services in extreme scenarios. However, most …

A popular approach to estimate a source location using time difference of arrival (TDOA)
measurements is to construct an objective function based on the maximum likelihood (ML) …

This article studies the problem of localization and tracking of a mobile target ship with an
autonomous underwater vehicle (AUV). A hybrid acoustic-optical underwater communication …

Estimating the location of a target is essential for many applications such as asset tracking,
navigation, and data communications. Time-difference-of-arrival (TDOA) based localization …

In this letter, we propose a novel method to disambiguate the phase-difference of a single-frequency
signal observed between a pair of spatially separated sensors, with inter-sensor …

A novel instantaneous method for Global Navigation Satellite System (GNSS) attitude
determination using a new phase-difference ambiguity resolution approach is presented. A triple-…

As a key enabler of Terahertz (THz)-based wireless technologies, large-scale multiple-input-multiple-output
systems are well known for their advantages in both communication and …

Linear discriminant analysis (LDA) is a widely used technique for data classification. The
method offers adequate performance in many classification problems, but it becomes inefficient …
