ODMA-based MIMO Massive Unsourced Random Access with Soft-Output Polar Codes
Tianya Li, Xiaoran Zhang, Nan Hu +4
This paper investigates the design of the on-off division multiple access (ODMA) transmission scheme for multiple-input multiple-output (MIMO) massive unsourced random access (URA)…
Media Meets Communication in 6G: Fundamentals, Key Technologies, and Applications
Bingyan Xie, Longyu Zhou, Zihan Chen +9
The rapid advancement of sixth-generation (6G) networks is accelerating the convergence of media intelligence and communication intelligence, driving media communication beyond con…
On the Gaussian-Quadratic Rate-Distortion Function for Vector Sources with Individual Distortion Constraints
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper investigates the Gaussian-quadratic lossy compression with arbitrary source length under individual distortion constraints. The rate-distortion function (RDF) is lower-b…
Semantic Noise Aided Secure Image Transmission over MIMO Fading Channels
Xue Han, Biqian Feng, Ting Zhou +5
Existing semantic communications have exhibited satisfactory performance in many tasks, but secure image transmission remains insufficiently explored. We propose a novel secure ima…
Towards World Model-Empowered Integrated Sensing, Communication, and Decision for Complex Unmanned Systems
Xue Han, Yongpeng Wu, Meng Shen +6
Complex unmanned systems comprising satellites, unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), and quadruped robots are increasingly deployed to perform large-sc…
Polar Decoding Tree Pruning Based on Soft Output Extraction
Li Shen, Yongpeng Wu, Wenjun Zhang
Although the successive cancellation list (SCL) decoding of polar codes exhibits excellent performance, it retains many decoding paths in the list with negligible contribution to t…
