Semantic communications focus on the transmission of semantic features. In this letter, we consider a task-oriented multi-user communication system for multimodal data transmission. Particularly, partial users transmit images while others texts to inquiry information about images. To exploit correlation among from multiple users, propose deep neural network enabled system, named MU-DeepSC, exec...

Abstract Task-oriented programming ( top ) is a new paradigm for specifying multi-user workflows. To reason formally about programs, formal language called TopHat has been designed, together with its operational semantics. For proving properties task-oriented it desirable to know when two -programs are semantically equivalent. This paper aims answer this question. We show that task can be in ei...
