Visible Light Positioning with Intelligent Reflecting Surfaces under Mismatched Orientations
Issifu Iddrisu, Sinan Gezici
Accurate localization can be performed in visible light systems in non-line-of-sight (NLOS) scenarios by utilizing intelligent reflecting surfaces (IRSs), which are commonly in the…
RIS-Aided NLoS Monostatic Sensing under Mobility and Angle-Doppler Coupling
Mahmut Kemal Ercan, Musa Furkan Keskin, Sinan Gezici +1
We investigate the problem of reconfigurable intelligent surface (RIS)-aided monostatic sensing of a mobile target under line-of-sight (LoS) blockage considering a single antenna,…
Joint RIS Phase Profile Design and Power Allocation for Parameter Estimation in Presence of Eavesdropping
Erfan Mehdipour Abadi, Ayda Nodel Hokmabadi, Sinan Gezici
We consider secure transmission of a deterministic complex-valued parameter vector from a transmitter to an intended receiver in the presence of an eavesdropper in a reconfigurable…
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…
