6G卫星网络的语义通信架构和编解码研究OA

As 6G technology evolves toward ultra-high speed,extremely low latency and global coverage,semantic communication,as a new generation of intelligent communication paradigm,can effectively address issues such as redundant data transmission and cross-system compatibility in traditional communication through deep integration with artificial intelligence technologies.Semantic communi-cation promotes the evolution of network architecture toward a combined semantic cognitive architecture of centralization and distribu-tion,achieving cross-scenario semantic interoperability through semantic knowledge base management,and optimizing end-to-end se-mantic transmission efficiency by relying on model,resource,and strategy management.In response to the problem of limited space-based resources in 6G satellite communication,end-to-end streaming speech codec is developed,and a multimodal semantic communi-cation test system is constructed.In experiments of Zhongxing-6D satellite,the breakthrough application prospects of semantic commu-nication in satellite and emergency scenarios were demonstrated,providing key technical support for the construction of 6G intelligent communication networks.
