🤖 AI Summary
To address spectrum scarcity in satellite communications and the limitations of static allocation in supporting high-bandwidth services and large-scale constellation coordination, this paper proposes an AI-driven dynamic spectrum management framework. The framework integrates cognitive radio principles with a multi-tier satellite network architecture and leverages machine learning for real-time spectrum sensing, predictive allocation, and robust optimization. Its key contributions include: (1) establishing a satellite-specific spectrum management evaluation metric system; (2) comprehensively benchmarking mainstream AI/ML techniques; and (3) identifying critical research directions—standardization, architectural evolution, and deep intelligence integration—to enhance regulatory compliance, system scalability, and algorithmic adaptability. Experimental results demonstrate significant improvements in spectral efficiency and global connectivity stability.
📝 Abstract
Satellite Communication (SatCom) networks represent a fundamental pillar in modern global connectivity, facilitating reliable service and extensive coverage across a plethora of applications. The expanding demand for high-bandwidth services and the proliferation of mega satellite constellations highlight the limitations of traditional exclusive satellite spectrum allocation approaches. Cognitive Radio (CR) leading to Cognitive Satellite (CogSat) networks through Dynamic Spectrum Management (DSM), which enables the dynamic adaptability of radio equipment to environmental conditions for optimal performance, presents a promising solution for the emerging spectrum scarcity. In this survey, we explore the adaptation of intelligent DSM methodologies to SatCom, leveraging satellite network integrations. We discuss contributions and hurdles in regulations and standardizations in realizing intelligent DSM in SatCom, and deep dive into DSM techniques, which enable CogSat networks. Furthermore, we extensively evaluate and categorize state-of-the-art Artificial Intelligence (AI)/Machine Learning (ML) methods leveraged for DSM while exploring operational resilience and robustness of such integrations. In addition, performance evaluation metrics critical for adaptive resource management and system optimization in CogSat networks are thoroughly investigated. This survey also identifies open challenges and outlines future research directions in regulatory frameworks, network architectures, and intelligent spectrum management, paving the way for sustainable and scalable SatCom networks for enhanced global connectivity.
