Unified Analytical Framework for Emergency RIS-UAV Networks Under Practical Impairments
Yinong Chen, Wenchi Cheng, Jingqing Wang +1
Heterogeneous unmanned aerial vehicle (UAV) networks embedded with reconfigurable intelligent surfaces (RISs) present a promising paradigm for emergency wireless communications (EW…
Subspace Fusion Sensing for Cooperative ISAC
Yining Xu, Cunhua Pan, Jun Tang +2
This paper proposes a subspace fusion sensing algorithm for cooperative integrated sensing and communication. First, we stack the received signals from access points (APs) into a t…
Rotatable Antenna-array-enhanced Direction-sensing for Low-altitude Communication Network: Method and Performance
Jinbing Jiang, Feng Shu, Bin Deng +5
In a practical multi-antenna receiver, each element of the receive antenna array has a directive antenna pattern, which is still not fully explored and investigated in academia and…
Towards Reliable Emergency Wireless Communications over SAGINs: A Composite Fading and QoS-Centric Perspective
Yinong Chen, Wenchi Cheng, Jingqing Wang +2
In emergency wireless communications (EWC) scenarios, ensuring reliable, flexible, and high-rate transmission while simultaneously maintaining seamless coverage and rapid response…
Data-Importance-Aware Power Allocation for Adaptive Semantic Communication in Computer Vision Applications
Chunmei Xu, Yi Ma, Rahim Tafazolli +1
Life-transformative applications such as immersive extended reality are revolutionizing wireless communications and computer vision (CV). This paper presents a novel framework for…
Ambiguity Function Analysis and Optimization of Frequency-Hopping MIMO Radar with Movable Antennas
Xiang Chen, Ming-Min Zhao, Min Li +3
In this paper, we propose a movable antenna (MA)-enabled frequency-hopping (FH) multiple-input multiple-output (MIMO) radar system and investigate its sensing resolution. Specifica…
