Special Issue Information
Dear Colleagues,
Cognitive Radio Systems (CRS) continue to play a pivotal role in addressing the spectrum scarcity and adaptability challenges of modern wireless communication. By enabling intelligent, context-aware spectrum access, and dynamic resource allocation, CRS are critical enablers of next-generation wireless networks.
Information theory provides the foundational framework for analyzing, modeling, and optimizing key functions of CRS, including spectrum sensing, interference management, and adaptive coding. Over the years, information-theoretic tools, such as mutual information metrics, entropy-based decision-making, and rate-distortion methods, have advanced the reliability, efficiency, and security of CRS in increasingly dynamic and heterogeneous environments.
A new wave of emerging technologies is significantly expanding the design space and capabilities of CRS. Innovations such as reconfigurable intelligent surfaces (RIS), extremely large antenna arrays (ELAAs), near-field communication, and novel flexible antenna architectures—including movable, fluid, and pinching antennas—are reshaping how wireless environments can be engineered and controlled. These advancements open both new challenges and exciting opportunities for the application and extension of information-theoretic principles in the design of next-generation CRS.
This Special Issue invites contributions that explore both theoretical foundations and practical innovations at the intersection of information theory, CRS, and emerging wireless technologies. We welcome submissions on topics including, but not limited to the following:
- Information-theoretic modeling and analysis for CRS with RIS;
- Information-theoretic advances with ELAA design and near-field communications;
- Entropy- and mutual information-based spectrum sensing and decision-making;
- Rate-distortion and adaptive coding strategies for dynamic CRS environments;
- New flexible antenna technologies, including movable, fluid, and pinching antenna systems, and their impact on CRS capacity and adaptability;
- Interference modeling, coexistence strategies, and robust spectrum sharing;
- Machine learning methods grounded in information theory for CRS optimization;
- Real-time decision-making algorithms and online learning in uncertain spectral environments;
- Energy-aware and ultra-reliable CRS enabled by emerging technologies.
We invite researchers and practitioners to contribute to this evolving field and help shape the future of intelligent wireless communication.
