CoLA: Multi-VLA Coordination via Learned Adapters
Ahaskar Kashyap, Jiawen Zong, Boyu Ma +4
Vision-Language-Action (VLA) models are typically deployed as isolated single-agent policies. When several such agents share a workspace, they can coordinate implicitly, by observi…
2D Coprime Pilots for Delay-Doppler Sensing in OFDM-ISAC Systems
Guanping Shang, Zeyan Zhuang, Anzheng Tang +2
Integrated Sensing and Communication (ISAC) is envisioned to endow future 6G systems with seamless sensing capabilities. To support efficient sensing with minimum communication ove…
A Unified Framework for Characterizing General MIMO Channels
Zeyan Zhuang, Anzheng Tang, Xin Zhang +2
Modern MIMO systems are evolving toward higher-dimensional and more flexible architectures, such as distributed and holographic MIMO, offering substantial benefits while giving ris…
Channel Estimation for XL-MIMO Systems with Decentralized Baseband Processing: Integrating Local Reconstruction with Global Refinement
Anzheng Tang, Jun-Bo Wang, Yijin Pan +6
In this paper, we investigate the channel estimation problem for extremely large-scale multiple-input multiple-output (XL-MIMO) systems with a hybrid analog-digital architecture, i…
Revisiting XL-MIMO Channel Estimation: When Dual-Wideband Effects Meet Near Field
Anzheng Tang, Jun-Bo Wang, Yijin Pan +4
The deployment of extremely large antenna arrays (ELAAs) in extremely large-scale multiple-input multiple-output (XL-MIMO) systems introduces significant near-field effects, such a…
Spatially Non-Stationary XL-MIMO Channel Estimation: A Three-Layer Generalized Approximate Message Passing Method
Anzheng Tang, Jun-Bo Wang, Yijin Pan +4
In this paper, channel estimation problem for extremely large-scale multi-input multi-output (XL-MIMO) systems is investigated with the considerations of the spherical wavefront ef…
Joint Visibility Region and Channel Estimation for Extremely Large-scale MIMO Systems
Anzheng Tang, Jun-bo Wang, Yijin Pan +5
In this work, we investigate the joint visibility region (VR) detection and channel estimation (CE) problem for extremely large-scale multiple-input-multiple-output (XL-MIMO) syste…
