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…
Goal-oriented Tensor: Beyond Age of Information Towards Semantics-Empowered Goal-Oriented Communications
Aimin Li, Shaohua Wu, Sumei Sun +1
Optimizations premised on open-loop metrics such as Age of Information (AoI) indirectly enhance the system's decision-making utility. We therefore propose a novel closed-loop metri…
Coalition Game based User Association for mmWave Mobile Relay Systems in Rail Traffic Scenarios
Chen Chen, Yong Niu, Shiwen Mao +6
Rail transportation, especially, high-speed rails (HSR), is an important infrastructure for the development of national economy and the promotion of passenger experience. Due to th…
Robust Beamforming Design for Covert Communications
Shuai Ma, Yunqi Zhang, Hang Li +4
In this paper, we consider a common unicast beamforming network where Alice utilizes the communication to Carol as a cover and covertly transmits a message to Bob without being rec…
A Novel High-Rate Polar-Staircase Coding Scheme
Bowen Feng, Jian Jiao, Liu Zhou +3
The long-haul communication systems can offer ultra high-speed data transfer rates but suffer from burst errors. The high-rate and high-performance staircase codes provide an effic…
