Adaptive Source-Channel Coding for Multi-User Semantic and Data Communications
Kai Yuan, Dongxu Li, Jianhao Huang +2
This paper considers a multi-user semantic and data communication (MU-SemDaCom) system, where a base station (BS) simultaneously serves users with different semantic and data tasks…
Adaptive Source-Channel Coding for Semantic Communications
Dongxu Li, Kai Yuan, Jianhao Huang +4
Semantic communications (SemComs) have emerged as a promising paradigm for joint data and task-oriented transmissions, combining the demands for both the bit-accurate delivery and…
D-JSCC: Digital Deep Joint Source-channel Coding for Semantic Communications
Jianhao Huang, Kai Yuan, Chuan Huang +1
Semantic communications (SemCom) have emerged as a new paradigm for supporting sixth-generation applications, where semantic features of data are transmitted using artificial intel…
Fundamental Limitation of Semantic Communications: Neural Estimation for Rate-Distortion
Dongxu Li, Jianhao Huang, Chuan Huang +3
This paper studies the fundamental limit of semantic communications over the discrete memoryless channel. We consider the scenario to send a semantic source consisting of an observ…
