Blind Beamforming for Coverage Enhancement with Intelligent Reflecting Surface
Fan Xu, Jiawei Yao, Wenhai Lai +4
Conventional policy for configuring an intelligent reflecting surface (IRS) typically requires channel state information (CSI), thus incurring substantial overhead costs and facing…
Coordinating Multiple Intelligent Reflecting Surfaces without Channel Information
Fan Xu, Jiawei Yao, Wenhai Lai +4
Conventional beamforming methods for intelligent reflecting surfaces (IRSs) or reconfigurable intelligent surfaces (RISs) typically entail the full channel state information (CSI).…
A Linear Time Algorithm for the Optimal Discrete IRS Beamforming
Shuyi Ren, Kaiming Shen, Xin Li +2
It remains an open problem to find the optimal configuration of phase shifts under the discrete constraint for intelligent reflecting surface (IRS) in polynomial time. The above pr…
Configuring Intelligent Reflecting Surface with Performance Guarantees: Optimal Beamforming
Yaowen Zhang, Kaiming Shen, Shuyi Ren +3
This work proposes linear time strategies to optimally configure the phase shifts for the reflective elements of an intelligent reflecting surface (IRS). Specifically, we show that…
Configuring Intelligent Reflecting Surface with Performance Guarantees: Blind Beamforming
Shuyi Ren, Kaiming Shen, Yaowen Zhang +3
This work gives a blind beamforming strategy for intelligent reflecting surface (IRS), aiming to boost the received signal-to-noise ratio (SNR) by coordinating phase shifts across…
Anion charge-lattice volume dependent Li ion migration in compounds with the face-centered cubic anion frameworks
Zhenming Xu, Xin Chen, Ronghan Chen +2
The proper design principles are essential for the efficient development of superionic conductors. However, the existing design principles are mainly proposed from the perspective…
