Secure Wireless Information Transfer and Energy Harvesting in HAPS-Based Network
Khaled Humadi, Gunes Karabulut-Kurt, Wessam Ajib +1
High-altitude platform station (HAPS) serves as a promising enabler for wide-area connectivity of low-power wireless devices, particularly in remote and underserved regions. Howeve…
PASS-Assisted RSMA under Imperfect SIC: Joint Antenna Activation and Resource Allocation
Saeid Pakravan, Imene Trigui, Wessam Ajib +1
The performance of rate-splitting multiple access (RSMA) can be severely affected by imperfect successive interference cancellation (SIC) in practical wireless systems. This paper…
Performance Analysis of Fluid Antenna-Assisted Over-the-Air Federated Learning Under Spatially Correlated Fading
Mohsen Ahmadzadeh, Saeid Pakravan, Wessam Ajib +3
Fluid antenna (FA) technology has recently emerged as an effective means of exploiting spatial diversity through position-domain reconfigurability. This paper investigates the inte…
Copula-Based Analysis of Fluid Antenna-Assisted Over-the-Air Computation
Saeid Pakravan, Mohsen Ahmadzadeh, Wessam Ajib +2
This letter studies an uplink over-the-air computation (AirComp) framework in which multiple user equipments are equipped with fluid-antenna (FA) arrays and operate over spatially…
Pinching Antenna System-Assisted Hybrid AirComp-NOMA Uplink: Joint Precoding and Antenna Placement Optimization
Saeid Pakravan, Imene Trigui, Wessam Ajib +1
This paper studies a pinching antenna system (PAS)-assisted hybrid uplink architecture that integrates over-the-air computation (AirComp) and non-orthogonal multiple access (NOMA)…
Impact of Position Uncertainty on the Secrecy Performance of Pinching Antenna Systems
Saeid Pakravan, Imene Trigui, Wessam Ajib +1
This paper investigates the secrecy performance of pinching-antenna systems (PAS) under practical pinching-position activation uncertainty. By dynamically selecting the radiation p…
