1、1/155AbstractIn the past few decades,research in the field of communication has mainly focused on howto accurately and effectively transmit symbols from the transmitter to the receiver,known assyntactic communication.Along with the development of wireless communication systems,system capacity has gr

2、adually approached the Shannon limit.Claude Shannon and WarrenWeaver categorized semantic communication as the second layer of communication.Unliketraditional communication,which aims for the accurate transmission of symbols,the primarygoal of semantic communication is to achieve the accurate exchan

3、ge of semantic information.Semantic communication focuses on conveying the meaning and significance of information,rather than just focusing on the symbols themselves.It is mainly used to address how toaccurately convey the meaning of transmitted symbols and how the receiver can influence thesystem

4、behavior in the desired way.Semantic communication can significantly improvecommunication efficiency through the extraction,coding,and transmission of semanticinformation.With the vigorous development of a new generation of communication and artificialintelligence technologies,semantic communication

5、 has shown broad application prospects infields such as human-computer interaction,holographic communication,and intelligentmanufacturing,receiving extensive attention fromacademic and industry communitiesworldwide.This white paper comprehensively introduces semantic communication in terms of the ba
