Neural Network-Assisted RIS Weight Optimization for Spatial Nulling in Distorted Reflector Antenna Systems
Xinrui Li, R. Michael Buehrer
Reconfigurable intelligent surfaces (RIS) have recently been proposed as an effective means for spatial interference suppression in large reflector antenna systems. Existing RIS we…
On the Limits of Coherent Time-Domain Cancellation of Radio Frequency Interference
Xinrui Li, R. Michael Buehrer
In many sensing (viz., radio astronomy) and radar applications, the received signal of interest (SOI) exhibits a significantly wider bandwidth or weaker power than the interference…
RIS-Aided Spatial Nulling: Algorithms, Analysis, and Nulling Limits
Xinrui Li, R. Michael Buehrer, Steven W. Ellingson
Reconfigurable Intelligent Surfaces (RIS) have recently gained attention as a means to dynamically shape the wireless propagation environment through programmable reflection contro…
Integrated Localization and Communication with Sparse MIMO: Will Virtual Array Technology also Benefit Wireless Communication?
Hongqi Min, Xinrui Li, Ruoguang Li +1
For the 6G wireless networks, achieving high-performance integrated localization and communication (ILAC) is critical to unlock the full potential of wireless networks. To simultan…
