Most ultrawideband (UWB) location systems already proposed for position estimation have
only been individually evaluated for particular scenarios. For a fair performance comparison …

WiFi fingerprinting, one of the most popular methods employed in indoor positioning,
currently faces two major problems: lack of robustness to short and long time signal changes …

Several UWB location systems have already been proposed for accurate position
estimation. These UWB systems, some available at commercial level, and others …

Indoor localization has become a mature research area, but further scientific developments
are limited due to the lack of open datasets and corresponding frameworks suitable to …

The development of indoor positioning solutions using smartphones is a growing activity

Age-related cognitive impairment is generally characterized by gradual memory loss and
decision-making difficulties. The aim of this study is to investigate multi-level support and …

In this paper, we present a 3-D ultrasonic measurement technique that uses direct sequence
spread spectrum (DSSS) with simultaneous multiple code-division multiple access (CDMA) …

Depth map** can be carried out by ultrasound measuring devices using the time of flight
method. Ultrasound measurements are favorable in such environments, where the light or …

Fingerprinting is widely used for indoor positioning, where pattern matching techniques are
usually applied to signals from APs or Beacons. However, the real-time monitoring of the …

This dissertation addresses a bidirectional scheme of Ultra-Wideband (UWB)-based
