On the performance of linear least-squares estimation in wireless positioning systems
(IEEE, 2008-05)
A common technique for wireless positioning is to estimate time-of-arrivals (TOAs) of signals traveling between a target node and a number of reference nodes, and then to determine the position of the target node based on ...
Theoretical limits for estimation of vital signal parameters using impulse radio UWB
(IEEE, 2007)
In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of vital signal parameters, such as respiration and heart-beat rates, using ultra-wideband (UWB) pulses are derived. In addition, a simple closed-form CRLB ...
