On the Sum of Inverse Gamma RVs and its Application to Wireless Communications Networks
Petros S. Bithas, Liang Yang, Qiuming Zhu +2
Investigating the statistics of the sum of random variables (RVs) is fundamental in wireless communication systems, as it can be used to accurately estimate their performance. In t…
GenAI-Enhanced Digital Twins for Predictive Interference Management in Ultra-Dense Networks
Afan Ali, Ali Arshad Nasir, Daniel Benevides da Costa
Ultra-dense indoor next-generation networks suffer severe interference from mobility-induced blockages and localized multi-user hotspots that conventional digital twins~(DTs) canno…
Cognitive Digital Twins for Self-Aware Channel Estimation
Afan Ali, Ali Arshad Nasir, Daniel Benevides da Costa
Artificial intelligence (AI) and machine learning (ML)-based channel estimators silently degrade when propagation conditions drift from their training distributions. This letter pr…
Cooperative NOMA Meets Emerging Technologies: A Survey for Next-Generation Wireless Networks
Mahmoud M. Salim, Suhail I. Al-Dharrab, Daniel Benevides Da Costa +1
The emerging demands of sixth-generation wireless networks, such as ultra-connectivity, native intelligence, and cross-domain convergence, are bringing renewed focus to cooperative…
Beamfocusing and Power Allocation for AN-Based PLS in Multiuser XL-MIMO with Multiple Eavesdroppers
Xiangjun Ma, Ali Arshad Nasir, Daniel Benevides da Costa
This paper investigates the downlink (DL) physical layer security (PLS) in a near-field (NF) extra-large multiple-input multiple-output MIMO (XL-MIMO) system. To enhance the secrec…
Sensing-aided Near-Field Secure Communications with Mobile Eavesdroppers
Yiming Xu, Mingxuan Zheng, Dongfang Xu +2
The additional degree of freedom (DoF) in the distance domain of near-field communication offers new opportunities for physical layer security (PLS) design. However, existing works…
