Least squares algorithms for time-of-arrival-based mobile location

TL;DR: It is shown that the CWLS estimator yields better performance than the LS method and achieves both the Crame/spl acute/r-Rao lower bound and the optimal circular error probability at sufficiently high signal-to-noise ratio conditions.
Journal ArticleDOI

Time-of-arrival based localization under NLOS conditions

TL;DR: A residual test (RT) is proposed that can simultaneously determine the number of line-of-sight (LOS) BS and identify them and then, localization can proceed with only those LOS BS.
Journal ArticleDOI

Joint Range and Angle Estimation Using MIMO Radar With Frequency Diverse Array

TL;DR: An unambiguous approach for joint range and angle estimation is devised for multiple-input multiple-output (MIMO) radar with frequency diverse array (FDA), which is capable of employing a small frequency increment across the array elements.
Journal ArticleDOI

A constrained least squares approach to mobile positioning: algorithms and optimality

TL;DR: This paper presents a constrained weighted least squares (CWLS) mobile positioning approach that encompasses all the above described measurement cases and shows that all the developed CWLS location estimators achieve zero bias and the Cramér-Rao lower bound approximately when measurement error variances are small.
Journal ArticleDOI

Transmit Subaperturing for Range and Angle Estimation in Frequency Diverse Array Radar

TL;DR: This paper proposes a transmit subaperturing scheme on the FDA radar for range and angle estimation of targets to divide the FDA elements into multiple subarrays and optimize the transmit beamspace matrix with the use of convex optimization.
