摘要
随着6G超级无线宽带业务的涌现,数据速率需求达到新的高峰。语义通信通过收发双方的知识共享和语义理解,能够减少传输信息量,降低带宽需求,具有良好的应用前景。聚焦语义通信的编解码技术和端到端传输技术,结合其业务特点和安全性需求,重点阐述语义通信的高效编解码和传输技术。此外,结合已有研究成果,探讨语义通信存在的挑战并展望其未来发展方向。
With the emergence of 6G super wireless broadband services,the data rate demand reaches new heights.Semantic communication,depending on knowledge sharing and semantic understanding between the transmitter and the receiver,shows a potential on the bandwidth reduction due to the less amount if data needed to be transmitted.This paper focuses on the semantic coding/decoding technology and end-to-end semantic transmission technology,from the perspectives of the service characteristics and security requirements.In addition,based on the existing research results,it points out the challenges of semantic communication and discusses the perspective of the future work in this research area.
