Metasurface-Enabled Superheterodyne Transmitter With Decoupled Harmonic-Free Signal Generation and Precoding
Xuehui Dong, Miyu Feng, Chen Shao +6
The evolution of programmable metasurfaces (PM) from passive beamforming to active information transmission marks a paradigm shift for next-generation wireless systems. However, th…
Flexible Multi-Beam Synthesis and Directional Suppression Through Transmissive RIS
Rujing Xiong, Ke Yin, Jialong Lu +3
Despite extensive research on reconfigurable intelligent surfaces (RISs) in recent years, existing beamforming methods still face significant challenges in achieving flexible and r…
Design and Optimization on Successive RIS-assisted Multi-hop Wireless Communications
Rujing Xiong, Jialong Lu, Jianan Zhang +4
As an emerging wireless communication technology, reconfigurable intelligent surface (RIS) has become a basic choice for providing signal coverage services in scenarios with dense…
Optimal Beamforming of RIS-Aided Wireless Communications: An Alternating Inner Product Maximization Approach
Rujing Xiong, Tiebin Mi, Jialong Lu +4
This paper investigates a general discrete -norm maximization problem, with the power enhancement at steering directions through reconfigurable intelligent surfaces (RISs)…
Multi-user ISAC through Stacked Intelligent Metasurfaces: New Algorithms and Experiments
Ziqing Wang, Hongzheng Liu, Jianan Zhang +5
This paper investigates a Stacked Intelligent Metasurfaces (SIM)-assisted Integrated Sensing and Communications (ISAC) system. An extended target model is considered, where the BS…
Decentralized Uncoded Storage Elastic Computing with Heterogeneous Computation Speeds
Wenbo Huang, Xudong You, Kai Wan +2
Elasticity plays an important role in modern cloud computing systems. Elastic computing allows virtual machines (i.e., computing nodes) to be preempted when high-priority jobs aris…
Asymptotic CRB Analysis of Random RIS-Assisted Large-Scale Localization Systems
Zhengyu Wang, Hongzheng Liu, Rujing Xiong +2
This paper studies the performance of a randomly RIS-assisted multi-target localization system, in which the configurations of the RIS are randomly set to avoid high-complexity opt…
