Active RISs: Signal Modeling, Asymptotic Analysis, and Beamforming Design
Zijian Zhang, Linglong Dai, Xibi Chen +4
Reconfigurable intelligent surfaces (RISs) have emerged as a candidate technology for future 6G networks. However, due to the "multiplicative fading" effect, the existing passive R…
Electromagnetic Information Theory: Fundamentals, Modeling, Applications, and Open Problems
Jieao Zhu, Zhongzhichao Wan, Linglong Dai +2
Traditional massive multiple-input multiple-output (MIMO) information theory adopt non-physically consistent assumptions, including white-noised, scalar-quantity, far-field, discre…
Deep Reinforcement Learning for IRS Phase Shift Design in Spatiotemporally Correlated Environments
Spilios Evmorfos, Athina P. Petropulu, H. Vincent Poor
The paper studies the problem of designing the Intelligent Reflecting Surface (IRS) phase shifters for Multiple Input Single Output (MISO) communication systems in spatiotemporally…
Impact of NOMA on Age of Information: A Grant-Free Transmission Perspective
Z. Ding, R. Schober, H. V. Poor
The aim of this paper is to characterize the impact of non-orthogonal multiple access (NOMA) on the age of information (AoI) of grant-free transmission. In particular, a low-comple…
On the Need of Neuromorphic Twins to Detect Denial-of-Service Attacks on Communication Networks
Holger Boche, Rafael F. Schaefer, H. Vincent Poor +1
As we are more and more dependent on the communication technologies, resilience against any attacks on communication networks is important to guarantee the digital sovereignty of o…
Energy Efficiency of Massive Random Access in MIMO Quasi-Static Rayleigh Fading Channels with Finite Blocklength
Junyuan Gao, Yongpeng Wu, Shuo Shao +2
This paper considers the massive random access problem in MIMO quasi-static Rayleigh fading channels. Specifically, we derive achievability and converse bounds on the minimum energ…
