Enhancements to linear least squares localization through reference selection and ML estimation
(IEEE, 2008-03-04)Linear least squares (LLS) estimation is a low complexity but sub-optimum method for estimating the location of a mobile terminal (MT) from some distance measurements. It requires selecting one of the fixed terminals (FTs) ... -
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 and a practical estimator for joint estimation of respiration and heartbeat rates using UWB impulse radio
(IEEE, 2007)In this paper, Cramer-Rao lower bounds are derived fo r joint estimation of respiration and heartbeat rates via impulse radio ultra-wideband signals. Generic models are employed for displacement functions due to respiration ... -
Theoretical limits for estimation of periodic movements in pulse-based UWB systems
(Institute of Electrical and Electronics Engineers, 2007)In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of signal parameters related to periodically moving objects in pulse-based ultra-wideband (UWB) systems are presented. The results also apply to estimation of ... -
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 ...
