Location estimation within the human body by means of wireless signals is becoming
popular for a variety of purposes, including wireless endoscopy using camera pills. The …

Recently, indoor localization has attracted considerable attention. More importantly, indoor
channel measurements and models are very essential to accurate characterization of the …

In this paper we study the effect of bandwidth on performance of positioning systems. We
introduce a benchmark for performance evaluation, distance measurement error (DME). We …

Wireless positioning technology based on TDOA is an effective supplement to GPS-denied
environment. However, traditional TDOA technologies often require precise time …

This chapter introduces important parameters used in modelling a wireless channel. It
provides a brief tutorial on the time of arrival (TOA)‐based localization technique and …

This paper deals with the impact of the time reversal (TR) processing on the performance of
an ultra wide band (UWB) location system. In a first part, we describe the topology of the …

The time-of-arrival (ToA)-based localization technique performs superior in line-of-sight
(LoS) conditions, and its accuracy degrades drastically in proximity of micro-metals and …

This preliminary paper deals with the impact of the Time Reversal (TR) processing on the
performance of an Ultra Wide Band (UWB) location system. In a first part, we describe the …

Recently, indoor localization has attracted considerable attention. More importantly, indoor
channel measurements and models are very essential to accurate characterization of the …

In order to solve the problem of the errors of moving target tracking in indoor positioning, the
ultra wide band tracking localization algorithm was proposed based on unscented Kalman …
