TW-TOA Based Positioning in the Presence of Clock Imperfections
Mohammad Reza Gholami, Sinan Gezici, Erik G. Ström
This paper studies the positioning problem based on two-way time-of-arrival (TW-TOA) measurements in asynchronous wireless sensor networks. Since the optimal estimator for this pro…
Statistics of the MLE and Approximate Upper and Lower Bounds - Part 2: Threshold Computation and Optimal Signal Design
Achraf Mallat, Sinan Gezici, Davide Dardari +1
Threshold and ambiguity phenomena are studied in Part 1 of this work where approximations for the mean-squared-error (MSE) of the maximum likelihood estimator are proposed using th…
Statistics of the MLE and Approximate Upper and Lower Bounds - Part 1: Application to TOA Estimation
Achraf Mallat, Sinan Gezici, Davide Dardari +2
In nonlinear deterministic parameter estimation, the maximum likelihood estimator (MLE) is unable to attain the Cramer-Rao lower bound at low and medium signal-to-noise ratios (SNR…
