Characterizing Information Accuracy in Timeliness-Based Gossip Networks
Emirhan Tekez, Melih Bastopcu, Sinan Gezici
We investigate information accuracy in timeliness-based gossip networks where the source evolves according to a continuous-time Markov chain (CTMC) with states and disseminates…
Pilot Distortion Design for ToA Obfuscation in Uplink OFDM Communication
Mahmut Kemal Ercan, Alireza Pourafzal, Musa Furkan Keskin +2
We study uplink orthogonal frequency-division multiplexing (OFDM) pilot distortion to deliberately obfuscate time-of-arrival (ToA) estimation at a single base station while preserv…
Decentralized Detection with Many Sensors: Optimality of Exchangeable and Identical Encoding Policies
Sina Sanjari, Naci Saldi, Sinan Gezici +1
We study a class of binary detection problems involving a single fusion center and a large or countably infinite number of sensors. Each sensor acts under a decentralized informati…
Optimal Decision Rules for Composite Binary Hypothesis Testing under Neyman-Pearson Framework
Yanglei Song, Berkan Dulek, Sinan Gezici
The composite binary hypothesis testing problem within the Neyman-Pearson framework is considered. The goal is to maximize the expectation of a nonlinear function of the detection…
Beyond Diagonal RIS Design for Parameter Estimation With and Without Eavesdropping
Ãzlem TuÄfe Demir, Sinan Gezici
In this letter, we investigate the transmission of a complex-valued parameter vector from a transmitter to an intended receiver, considering both the presence and absence of an eav…
Calibration in RIS-aided Integrated Sensing, Localization and Communication Systems
Reza Ghazalian, Pinjun Zheng, Hui Chen +6
Reconfigurable intelligent surfaces (RISs) are key enablers for integrated sensing and communication (ISAC) systems in the 6G communication era. With the capability of dynamically…
