Active Beyond-Diagonal RIS Empowered Heterogeneous Edge Computing: A Distributional Reinforcement Learning Approach
Tianyu Pang, Hongyu Li
Active beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) enables hybrid transmitting and reflecting mode to achieve effective signal amplification and full-space covera…
Antenna Coding Design for Pixel Antenna Empowered Rate-Splitting Multiple Access
Haobo Huang, Yijie Mao, Hongyu Li +1
This work explores the integration of pixel antennas and rate-splitting multiple access (RSMA) to enhance spectral efficiency in multi-user multiple-input single-output (MU-MISO) s…
Sparse Channel Estimation for Pixel Antennas: Addressing the Pilot Rank Deficiency
Yiting Chen, Yumeng Zhang, Hongyu Li
Composed of multiple interconnected pixels controlled by on/off RF switches, the pixel antenna can generate reconfigurable radiation patterns that can be further exploited to const…
Active Beyond-Diagonal Reconfigurable Intelligent Surfaces: Modeling, Architecture Design, and Optimization
Shanpu Shen, Hongyu Li, Matteo Nerini +2
Beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) are an emerging RIS 2.0 technology for future wireless communication. However, BD-RISs are primarily passive without a…
