Time-of-Arrival (ToA) estimation becomes extremely challenging for ultra-wideband ranging
systems in dense multipath environment with multiuser interference. In this paper, we …

Roundtrip time-of-arrival (ToA) measurements employing ultra-wideband (UWB) signals can
provide high-precision ranging information. However, the accuracy is degraded by multiuser …

We present a joint estimator of the time-of-arrival (TOA) and angle-of-arrival (AOA) for
impulse radio ultra-wideband (IR-UWB) localization systems in which an antenna array is …

In order to alleviate multiple access interference and multipath interference of ultra‐
wideband (UWB) system, we propose the orthogonal complementary code (OCC)‐based …

Les technologies d'impulsions radio (IR) à ultra large bande (UWB) n'est pas limitée aux
applications radar et de communications et s' avère très utile pour la localisation et le suivi …

Interference is a very common phenomenon in wireless communication systems. With the
Radio Frequency (RF) spectrum getting increasingly crowded due to the demand for high …

Time of arrival is a commonly used mechanism for geolocation. In many environments,
multipath propagation of RF signals limits accuracy. Wide bandwidths reduce the impact of …

The unlicensed use of the ultra wideband (UWB) spectrum has been allowed in May 2002
by the US federal communications commission (FCC)[1]. A signal is considered as UWB if its …
