Proposed Solutions (2)
knowledge-graph semantic communication with channel encryption: The proposed system preprocesses text into topic-annotated sentences, extracts them into a knowledge graph, securely transmits it using constellation diagonal transformation with MP-WFRFT, and recovers text via a transformer model.
