Feedback Control via Integrated Sensing and Communication: Uncertainty Optimisation
Touraj Soleymani, Mohamad Assaad, John S. Baras
This paper studies integrated sensing and communication (ISAC) coordination for feedback control tasks under shared platform constraints. We consider a cyber-physical system in whi…
Status Updating via Integrated Sensing and Communication: Freshness Optimisation
Touraj Soleymani, Mohamad Assaad, John S. Baras
In this paper, we study how sensing and communication should be jointly coordinated in integrated sensing and communication (ISAC) systems to maintain timely situational awareness…
Remote State Estimation over Unreliable Channels with Unreliable Feedback: Strategies and Limits
Touraj Soleymani, Mohamad Assaad, John S. Baras
In this article, we establish a comprehensive theoretical framework for remote estimation in a networked system composed of a source that is observed by a sensor, a remote monitor…
Networked Control with Hybrid Automatic Repeat Request Protocols
Touraj Soleymani, John S. Baras, Deniz Gündüz
We study feedback control of a dynamical process over a lossy channel equipped with a hybrid automatic repeat request protocol that connects a sensor to an actuator. The dynamical…
Consistency of Value of Information: Effects of Packet Loss and Time Delay in Networked Control Systems Tasks
Touraj Soleymani, John S. Baras, Siyi Wang +2
In this chapter, we study the consistency of the value of information$\unicode{x2014}$a semantic metric that claims to determine the right piece of information in networked control…
Foundations of Value of Information: A Semantic Metric for Networked Control Systems Tasks
Touraj Soleymani, John S. Baras, Sandra Hirche +1
In this chapter, we present our recent invention, i.e., the notion of the value of information$\unicode{x2014}$a semantic metric that is fundamental for networked control systems t…
Relation between Value and Age of Information in Feedback Control
Touraj Soleymani, John S. Baras, Karl H. Johansson
In this chapter, we investigate the value of information as a more comprehensive instrument than the age of information for optimally shaping the information flow in a networked co…
Enabling Cooperative Hybrid Beamforming in TDD-based Distributed MIMO Systems
Nariman Torkzaban, Amir Khojastepour, John S. Baras
Distributed massive MIMO networks are envisioned to realize cooperative multi-point transmission in next-generation wireless systems. For efficient cooperative hybrid beamforming,…
Blind Cyclic Prefix-based CFO Estimation in MIMO-OFDM Systems
Nariman Torkzaban, Amir Khojastepour, John S. Baras
Low-complexity estimation and correction of carrier frequency offset (CFO) are essential in orthogonal frequency division multiplexing (OFDM). In this paper, we propose a low-overh…
Multi-user Beam Alignment in Presence of Multi-path
Nariman Torkzaban, Mohammad A., Khojastepour +1
To overcome the high path-loss and the intense shadowing in millimeter-wave (mmWave) communications, effective beamforming schemes are required which incorporate narrow beams with…
Codebook Design for Composite Beamforming in Next-generation mmWave Systems
Nariman Torkzaban, Mohamamd A., Khojastepour +1
In pursuance of the unused spectrum in higher frequencies, millimeter wave (mmWave) bands have a pivotal role. However, the high path-loss and poor scattering associated with mmWav…
Stochastic Control with Stale Information--Part I: Fully Observable Systems
Touraj Soleymani, John S. Baras, Karl H. Johansson
In this study, we adopt age of information as a measure of the staleness of information, and take initial steps towards analyzing the control performance of stochastic systems with…
