Random Access Game in Fading Channels with Capture: Equilibria and Braess-like Paradoxes

open access: yes, 2011
The Nash equilibrium point of the transmission probabilities in a slotted ALOHA system with selfish nodes is analyzed. The system consists of a finite number of heterogeneous nodes, each trying to minimize its average transmission probability (or power ...

Performance analysis for a class of robust adaptive beamformers [PDF]

open access: yes, 2004
Robust adaptive beamforming is a key issue in array applications where there exist uncertainties about the steering vector of interest. Diagonal loading is one of the most popular techniques to improve robustness.

MIMO Interference Alignment Over Correlated Channels with Imperfect CSI

open access: yes, 2010
Interference alignment (IA), given uncorrelated channel components and perfect channel state information, obtains the maximum degrees of freedom in an interference channel. Little is known, however, about how the sum rate of IA behaves at finite transmit

A Cross‐Layer Spatial–Spectral Optimization Framework for Hybrid Routing and Load‐Balanced Channel Allocation in Intelligent Networks

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Rapid 5G/6G evolution demands cross‐layer resource management to address congestion, latency, and reliability in multi‐hop wireless networks. This paper proposes a TOHRP–LBCA framework using DSA and congestion−/topology−/interference‐aware routing and channel allocation, yielding throughput gains, lower latency, improved packet delivery, and higher ...

Deep neural network design with SLNR and SINR criterions for downlink power allocation in multi-cell multi-user massive MIMO systems

open access: yesICT Express, 2023
In this paper, we propose a deep learning approach for solving power allocation problems in massive MIMO networks. We use signal-to-interference-plus-noise-ratio (SINR) and signal-to-leak-plus-noise ratio (SLNR) criteria for linear precoder design to ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Taxonomy of IMT Interference on Aeronautical Systems

open access: yesRadio Science, Volume 61, Issue 4, April 2026.
Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...
