Abstract
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.
