Multi-Agent Orchestration of 3GPP Channel Estimators
I. Zakir Ahmed, Hamid Sadjadpour
Pilot-aided channel estimation is a decisive block in orthogonal frequency-division multiplexing (OFDM) receivers for both 5G New Radio (5G-NR) and Long-Term Evolution (LTE). A lar…
Deep Learning-Assisted UAV Localization Framework for Post-Disaster Search and Rescue Missions
Xiangjian Gao, Hamid R. Sadjadpour
The precise locating of trapped victims is arguably the most challenging issue in SAR operations, particularly when infrastructure is destroyed and SAR teams only have low-power be…
Age Dispersion and Higher-Order AoI in Status Update Systems
Mohammad Moltafet, Roy D. Yates, Marian Codreanu +1
We introduce and characterize \emph{age dispersion} as a measure of temporal consistency in status update systems. Age dispersion is defined as the difference between the ages of t…
Status Updating in Two-Way Delay Systems with Preemption
Jinxin Yang, Mohammad Moltafet, Hamid R. Sadjadpour
We consider a status update system consisting of a sampler, a sink, and a controller located at the sink. The controller sends requests to the sampler to generate and transmit stat…
Multi-Source M/G/1/1 Queues with Probabilistic Preemption
Mohammad Moltafet, Hamid R. Sadjadpour, Zouheir Rezki +2
We consider a multi-source status update system consisting of multiple independent sources, a single server, and a single sink. Each source generates packets according to a Poisson…
An Unconditionally Secure Encryption Scheme for IoBT Networks
Mohammad Moltafet, Hamid R. Sadjadpour, Zouheir Rezki
We consider an Internet of Battlefield Things (IoBT) system consisting of multiple devices that want to securely communicate with each other during a mission in the presence of an…
