RIS-Aided NLoS Monostatic Sensing under Mobility and Angle-Doppler Coupling

no code implementations12 Jan 2024 Mahmut Kemal Ercan, Musa Furkan Keskin, Sinan Gezici, Henk Wymeersch

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, full-duplex, and dual-functional radar-communications base station (BS).

Joint RIS Phase Profile Design and Power Allocation for Parameter Estimation in Presence of Eavesdropping

no code implementations25 Sep 2023 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 intelligent surface (RIS)-integrated environment.

RIS-aided Localization under Pixel Failures

no code implementations9 Feb 2023 Cuneyd Ozturk, Musa Furkan Keskin, Vincenzo Sciancalepore, Henk Wymeersch, Sinan Gezici

Reconfigurable intelligent surfaces (RISs) hold great potential as one of the key technological enablers for beyond-5G wireless networks, improving localization and communication performance under line-of-sight (LoS) blockage conditions.

On the Impact of Hardware Impairments on RIS-aided Localization

no code implementations25 May 2022 Cuneyd Ozturk, Musa Furkan Keskin, Henk Wymeersch, Sinan Gezici

We investigate a reconfigurable intelligent surface (RIS)-aided near-field localization system with single-antenna user equipment (UE) and base station (BS) under hardware impairments by considering a practical phase-dependent RIS amplitude variations model.

RIS-aided Near-Field Localization under Phase-Dependent Amplitude Variations

no code implementations27 Apr 2022 Cuneyd Ozturk, Musa Furkan Keskin, Henk Wymeersch, Sinan Gezici

The proposed method can successfully recover the performance loss of the AMML under a wide range of RIS parameters and effectively calibrate the RIS amplitude model online with the help of a user that has an a-priori unknown location.

Signaling Games for Log-Concave Distributions: Number of Bins and Properties of Equilibria

no code implementations15 Dec 2020 Ertan Kazıklı, Serkan Sarıtaş, Sinan Gezici, Tamás Linder, Serdar Yüksel

For sources with two-sided unbounded support, we prove that, for any finite number of bins, there exists a unique equilibrium.

Power Adaptation for Vector Parameter Estimation according to Fisher Information based Optimality Criteria

no code implementations20 Nov 2020 Doğa Gürgünoğlu, Berkan Dulek, Sinan Gezici

The optimal power adaptation problem is investigated for vector parameter estimation according to various Fisher information based optimality criteria.

Database Assisted Nonlinear Least Squares Algorithm for Visible Light Positioning in NLOS Environments

no code implementations28 Sep 2020 Ahmet Faruk Saz, Sinan Gezici

We propose an indoor localization algorithm for visible light systems by considering effects of non-line-of-sight (NLOS) propagation.

Quadratic Privacy-Signaling Games and the MMSE Information Bottleneck Problem for Gaussian Sources

no code implementations12 May 2020 Ertan Kazıklı, Sinan Gezici, Serdar Yüksel

We show that this MMSE Gaussian Information Bottleneck Problem admits a linear solution which is explicitly characterized in the paper.
