UWB localization algorithms
(John Wiley & Sons, 2009)
Mean acquisition time analysis of fixed-step serial search algorithms
In this paper, mean acquisition time (MAT) analysis of fixed-step serial search (FSSS) algorithms is presented. First, it is shown that the MAT of an FSSS algorithm can be obtained from that of a conventional serial search ...
Iterative ("Turbo") multiuser detectors for impulse radio systems
(Institute of Electrical and Electronics Engineers, 2008)
In recent years, there has been a growing interest in multiple access communication systems that spread their transmitted energy over very large bandwidths. These systems, which are referred to as ultra wide-band (UWB) ...
Position estimation via ultra-wide-band signals
The high time resolution of ultra-wide-band (UWB) signals facilitates very precise position estimation in many scenarios, which makes a variety applications possible. This paper reviews the problem of position estimation ...
Two-step time of arrival estimation for pulse-based ultra-wideband systems
In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information. One ...

Fundamental limits on time delay estimation in dispersed spectrum cognitive radio systems
In this paper, fundamental limits on time delay estimation are studied for cognitive radio systems, which facilitate opportunistic use of spectral resources. First, a generic Cramer-Rao lower bound (CRLB) expression is ...
On the performance of linear least-squares estimation in wireless positioning systems
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 ...
Enhancements to linear least squares localization through reference selection and ML estimation
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) ...
Theoretical limits for estimation of vital signal parameters using impulse radio UWB
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 ...
