Low-Complexity Channel Estimation Framework for Non-Square UPA-Assisted XL-MIMO Systems

Yilong Liu, Xi Yang, Binggui Zhou, Yu Han, Ting Liu, Shaodan Ma

Low-complexity channel state information acquisition is crucial for extremely large-scale multiple-input multiple-output (XL-MIMO) systems. However, practical deployments of non-square uniform planar arrays (UPAs) in hybrid-field environments face prohibitive computational comple…

Dynamic Speed Limit Control of Connected Automated Vehicles in Freeway Networks Considering Traffic Composition Uncertainty

Lei Wei, Yu Han, Haiyang Yu, Yunpeng Wang

Dynamic speed limit control has emerged as a promising strategy to improve freeway sustainability in mixed traffic environments with connected automated vehicles (CAVs). However, most existing approaches assume that the CAV penetration rate is deterministic and can be accurately…
