How Much Sensing Information Is Needed to Control an Unstable Linear System?
Ming Li, Fan Liu, Yifeng Xiong +4
Modern control systems increasingly rely on sensing to infer the system state before control actions can be taken. Yet a given observation mechanism may fail to preserve sufficient…
Sensing-Limited Control of Noiseless Linear Systems Under Nonlinear Observations
Ming Li, Fan Liu, Yifeng Xiong +2
This paper investigates the fundamental information-theoretic limits for the control and sensing of noiseless linear dynamical systems subject to a broad class of nonlinear observa…
From Ground to Sky: Architectures, Applications, and Challenges Shaping Low-Altitude Wireless Networks
Weijie Yuan, Yuanhao Cui, Jiacheng Wang +13
In this article, we introduce a novel low-altitude wireless network (LAWN), which is a reconfigurable, three-dimensional (3D) layered architecture. In particular, the LAWN integrat…
Low-Altitude Wireless Networks: The Next Horizon of Wireless Infrastructure
Yuanhao Cui, Jiali Nie, Weijie Yuan +5
Low-altitude airspace, roughly defined as the region up to 3000 meters above ground level, is envisioned as a new spatial domain for daily human and machine activities. This articl…
Integrated Sensing and Communications Over the Years: An Evolution Perspective
Di Zhang, Yuanhao Cui, Xiaowen Cao +10
Integrated Sensing and Communications (ISAC) enables efficient spectrum utilization and reduces hardware costs for beyond 5G (B5G) and 6G networks, facilitating intelligent applica…
Integrated Sensing and Communication: Towards Multifunctional Perceptive Network
Yuanhao Cui, Jiali Nie, Fan Liu +7
The capacity-maximization design philosophy has driven the growth of wireless networks for decades. However, with the slowdown in recent data traffic demand, the mobile industry ca…
