Near-Field Multi-User Communications via Polar-Domain Beamfocusing: Analytical Framework and Performance Analysis
Lin Chen, Ahmed Elzanaty, Mustafa A. Kishk +1
As wireless systems evolve toward higher frequencies and extremely large antenna arrays, near-field (NF) propagation becomes increasingly dominant. Unlike far-field (FF) communicat…
Near-Field Position and Orientation Tracking With Hybrid ELAA Architecture
Lin Chen, Xiaojun Yuan, Ying-Jun Angela Zhang
This paper investigates near-field (NF) position and orientation tracking of a multi-antenna mobile station (MS) using an extremely large antenna array (ELAA)-equipped base station…
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…
