World Model-Enabled Causal Digital Twins for Semantic Communications in Physical AI Systems
Lingyi Wang, Tingyu Shui, Walid Saad +1
Semantic communication has emerged as a promising paradigm for enabling goal-oriented networking. However, most existing semantic communication solutions are tailored to one-shot t…
Knowledge-Driven 3D Semantic Spectrum Map: KE-VQ-Transformer Based UAV Semantic Communication and Map Completion
Wei Wu, Lingyi Wang, Fuhui Zhou +2
Artificial intelligence (AI)-native three-dimensional (3D) spectrum maps are crucial in spectrum monitoring for intelligent communication networks. However, it is challenging to ob…
Knowledge Graph-Based Explainable and Generalized Zero-Shot Semantic Communications
Zhaoyu Zhang, Lingyi Wang, Wei Wu +2
Data-driven semantic communication is based on superficial statistical patterns, thereby lacking interpretability and generalization, especially for applications with the presence…
Cross-Layer Security for Semantic Communications: Metrics and Optimization
Lingyi Wang, Wei Wu, Fuhui Zhou +2
Different from traditional secure communication that focuses on symbolic protection at the physical layer, semantic secure communication requires further attention to semantic-leve…
