Rateless Stochastic Coding for Delay-constrained Semantic Communication

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Rulong Wang, Yong Xiao, , | Summary: We consider the problem of joint source-channel coding with distortion and perception constraints from a rateless perspective, the purpose of which is to settle the balance between reliability (distortion/perception) and effectiveness (rate) of transmission over uncertain channels. We […]
