Wireless Intelligence Needs a Cerebellum: Score-Based Foundation Models Toward Real-Time Physical-Layer Inference
Chang Cai, Boyu Teng, Xiaojun Yuan +1
Wireless intelligence requires not only large foundation models for network-wide planning and decision-making, but also a compact "cerebellum" for fast and precise physical-layer i…
Score-Based Turbo Message Passing for Plug-and-Play Compressive Imaging
Chang Cai, Hao Jiang, Xiaojun Yuan +1
Message-passing algorithms have been adapted for compressive imaging by incorporating various off-the-shelf image denoisers. However, these denoisers rely largely on generic or han…
Scoring ISAC: Benchmarking Integrated Sensing and Communications via Score-Based Generative Modeling
Lin Chen, Chang Cai, Huiyuan Yang +2
Integrated sensing and communications (ISAC) is a key enabler for next-generation wireless systems, aiming to support both high-throughput communication and high-accuracy environme…
Joint Activity Detection and Channel Estimation for Massive Connectivity: Where Message Passing Meets Score-Based Generative Priors
Chang Cai, Wenjun Jiang, Xiaojun Yuan +1
Massive connectivity supports the sporadic access of a vast number of devices without requiring prior permission from the base station (BS). In such scenarios, the BS must perform…
Score-Based Turbo Message Passing for Plug-and-Play Compressive Image Recovery
Chang Cai, Xiaojun Yuan, Ying-Jun Angela Zhang
Message passing algorithms have been tailored for compressive imaging applications by plugging in different types of off-the-shelf image denoisers. These off-the-shelf denoisers mo…
End-to-End Learning for Task-Oriented Semantic Communications Over MIMO Channels: An Information-Theoretic Framework
Chang Cai, Xiaojun Yuan, Ying-Jun Angela Zhang
This paper addresses the problem of end-to-end (E2E) design of learning and communication in a task-oriented semantic communication system. In particular, we consider a multi-devic…
Multi-Device Task-Oriented Communication via Maximal Coding Rate Reduction
Chang Cai, Xiaojun Yuan, Ying-Jun Angela Zhang
In task-oriented communications, most existing work designed the physical-layer communication modules and learning based codecs with distinct objectives: learning is targeted at ac…
RIS Partitioning Based Scalable Beamforming Design for Large-Scale MIMO: Asymptotic Analysis and Optimization
Chang Cai, Xiaojun Yuan, Ying-Jun Angela Zhang
In next-generation wireless networks, reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) systems are foreseeable to support a large number of a…
Hierarchical Passive Beamforming for Reconfigurable Intelligent Surface Aided Communications
Chang Cai, Xiaojun Yuan, Wenjing Yan +3
In reconfigurable intelligent surfaces (RISs) aided communications, the existing passive beamforming (PB) design involves polynomial complexity in the number of reflecting elements…
Two-Timescale Optimization for Intelligent Reflecting Surface Aided D2D Underlay Communication
Chang Cai, Huiyuan Yang, Xiaojun Yuan +1
The performance of a device-to-device (D2D) underlay communication system is limited by the co-channel interference between cellular users (CUs) and D2D devices. To address this ch…
