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…
Resonant Beam Communications: A New Design Paradigm and Challenges
Yuanming Tian, Dongxu Li, Chuan Huang +2
Resonant beam communications (RBCom), which adopt oscillating photons between two separate retroreflectors for information transmission, exhibit potential advantages over other typ…
Design and Performance of Resonant Beam Communications -- Part II: Mobile Scenario
Dongxu Li, Yuanming Tian, Chuan Huang +2
This two-part paper focuses on the system design and performance analysis for a point-to-point resonant beam communication (RBCom) system under both the quasi-static and mobile sce…
Design and Performance of Resonant Beam Communications -- Part I: Quasi-Static Scenario
Dongxu Li, Yuanming Tian, Chuan Huang +2
This two-part paper studies a point-to-point resonant beam communication (RBCom) system, where two separately deployed retroreflectors are adopted to generate the resonant beam bet…
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…
