Enhanced localization coverage with Non-Regenerative UWB relays
Real-time locating systems (RTLS) enable a number of
new important applications. Their performance is mainly limited
by wireless propagation impairments. This paper puts
forth the idea to enhance coverage and accuracy of RTLS in
the presence of severe non line-of-sight propagation conditions
using low complexity non-regenerative ultra-wide bandwidth
relays. A maximum likelihood position estimator is derived
and the feasibility of relay-based positioning scheme is
demonstrated
