Rate Loss Analysis for Multiple-Antenna NOMA with Limited Feedback
Ruizhan Shen, Hamid Jafarkhani
In the limited feedback downlink multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) system, both the effective channel gain and the channel direction need to…
Optimizing Cellular Networks for UAV Corridors via Quantization Theory
Saeed Karimi-Bidhendi, Giovanni Geraci, Hamid Jafarkhani
We present a new framework based on quantization theory to design cellular networks optimized for both legacy ground users and uncrewed aerial vehicle (UAV) corridors, dedicated ae…
Asynchronous Federated Learning with Bidirectional Quantized Communications and Buffered Aggregation
Tomas Ortega, Hamid Jafarkhani
Asynchronous Federated Learning with Buffered Aggregation (FedBuff) is a state-of-the-art algorithm known for its efficiency and high scalability. However, it has a high communicat…
Reconfigurable Intelligent Surface-Aided NOMA with Limited Feedback
Mojtaba Ahmadi Almasi, Hamid Jafarkhani
The design of feedback channels in frequency division duplex (FDD) systems is a major challenge because of the limited available feedback bits. We consider non-orthogonal multiple…
Analysis of UAV Corridors in Cellular Networks
Saeed Karimi-Bidhendi, Giovanni Geraci, Hamid Jafarkhani
In this article, we introduce a new mathematical framework for the analysis and design of UAV corridors in cellular networks, while considering a realistic network deployment, ante…
Gossiped and Quantized Online Multi-Kernel Learning
Tomas Ortega, Hamid Jafarkhani
In instances of online kernel learning where little prior information is available and centralized learning is unfeasible, past research has shown that distributed and online multi…
