In recent times, social and commercial interests in location-based services (LBS) are
significantly increasing due to the rise in smart devices and technologies. The global …

Ultra-wideband (UWB) positioning systems often operate in a non-line-of-sight (NLOS)
environment. NLOS propagation has become the main source of ultra-wideband indoor …

This two-part paper investigates the application of artificial intelligence (AI) and, in particular,
machine learning (ML) to the study of wireless propagation channels. In Part I of this article …

Non-line-of-sight (NLOS) propagation of radio signals can significantly degrade the
performance of ultra-wideband localization systems indoors, it is hence crucial to mitigate …

Emerging communication network applications including fifth-generation (5G) cellular and
the Internet-of-Things (IoT) will almost certainly require location information at as many …

In this survey, the currently available ultra-wideband-based non-line-of-sight (NLOS)
identification and error mitigation methods are presented. They are classified into several …

Ultra-wideband technology has found promising application in high accuracy localization
due to its high time resolution and through-wall propagation properties. However, its …

Localization using the time-of-arrival (ToA) of a wideband signal has the potential to achieve
high accuracy, thereby making it a promising choice for a variety of applications. However, a …

Ultrawideband (UWB) sensor technology is known to achieve high-precision indoor
localization accuracy in line-of-sight (LOS) environments, but its localization accuracy and …

For time-of-arrival-(TOA)-based indoor human tracking system, the wireless channel
between human body surface and external reference node can be regarded as the source of …
