Interference Management in Reverse TDD HAPS-Ground Networks: A Large System Analysis
Shasha Liu, Abla Kammoun, Mohamed-Slim Alouini
High-altitude platform stations (HAPSs) are expected to coexist with terrestrial networks (TNs) to provide seamless wide-area wireless connectivity in future sixth-generation (6G)…
Semi-Blind Channel Estimation for Dynamic NTN Systems via Spiked Random Matrix Theory
Xue Zhang, Abla Kammoun, Mohamed-Slim Alouini
Semi-blind channel estimation offers an attractive tradeoff between pilot overhead and estimation accuracy in large-scale wireless systems. However, reliable channel acquisition be…
Uplink MIMO Performance Analysis for Diverse HAPS Antenna Array Architectures
Shasha Liu, Abla Kammoun, Mohamed-Slim Alouini
High-altitude platform stations (HAPS) are promising components of 6G and beyond networks, where antenna array configuration is critical for achieving wide-area coverage and high c…
Three-Dimensional Spatial Correlation Modeling for Cylindrical mMIMO Arrays in HAPS
Shasha Liu, Abla Kammoun, Mohamed-Slim Alouini
High-altitude platform stations (HAPS) are envisioned as a key component of future wireless networks, enabling ultra-wide coverage and providing direct connectivity to users with c…
CRB-Based Resource Allocation in Multi-User Uplink Transmissions
Xue Zhang, Abla Kammoun, Mohamed-Slim Alouini
In this work, we study the design of receivers for uplink multi-user systems, aiming to estimate both the channel and the transmitted symbols. We consider two estimation strategies…
Sum Rate and Worst Case SINR Optimization in Multi HAPS Ground Integrated Networks
Shasha Liu, Hayssam Dahrouj, Abla Kammoun +1
Balancing throughput and fairness promises to be a key enabler for achieving large-scale digital inclusion in future vertical heterogeneous networks (VHetNets). In an attempt to ad…
