This curated Research Topic within the Signal Propagation section of Frontiers in Antennas and Propagation aims to spotlight cutting-edge research on Non-Line-of-Sight (NLOS) communication specifically tailored for the complex landscapes of urban canyons. Urban canyons, characterised by towering structures, intricate street layouts, and diverse building materials, present formidable challenges for wireless communication. This article collection seeks to gather contributions that explore innovative methodologies in antenna design, tailored propagation models, and smart signal processing to address the unique obstacles posed by urban canyon NLOS scenarios.
The focused objectives of this research topic are designed to deepen our understanding of urban canyon NLOS communication and promote advancements in the field:
Urban Canyon Characterization:
• Gather articles that employ advanced techniques, such as 3D modelling and imaging, to comprehensively characterise urban canyon environments. This includes analyses of building geometry, the impact of reflective surfaces, and the role of various construction materials in shaping signal propagation characteristics.
Specialized Antenna Solutions:
• Encourage contributions exploring antenna designs customised for urban canyon NLOS scenarios. This involves research on directional antennas with narrow beamwidths, adaptive beamforming strategies for dynamic adjustments, and innovative antenna arrays optimised for the specific geometries of urban canyons.
Context-Aware Propagation Models:
• Solicit articles that propose and validate propagation models extending beyond traditional line-of-sight paradigms. These models should account for the intricacies of urban canyon NLOS scenarios, incorporating features like reflective building facades, variations in surface materials, and dynamic environmental changes.
Smart Signal Processing Techniques:
• Compile contributions that delve into sophisticated signal processing techniques tailored for urban canyon environments. This includes advanced interference cancellation algorithms, deep learning-based channel estimation, and adaptive processing algorithms capable of responding to rapid changes in signal conditions.
Field-Tested Validation:
• Feature articles reporting on extensive field experiments conducted in real urban canyon settings. Emphasise contributions that validate proposed techniques in diverse urban environments, ensuring their robustness and applicability to real-world conditions.
Integration with Smart City Applications:
• Explore articles discussing the seamless integration of NLOS communication techniques into smart city applications. Assess their impact on intelligent transportation systems, urban surveillance networks, and broader urban Internet of Things (IoT) deployments.
This Research Topic aspires to showcase a cohesive body of research that advances the state-of-the-art in NLOS communication within urban canyons. By bringing together diverse perspectives and innovative solutions, this collection seeks to provide a comprehensive resource for researchers, practitioners, and policymakers working on improving wireless communication in challenging urban environments.
