Optimal Phase Design for RIS Channel Estimation
Chelsea L. Miller, Peter J. Smith, Pawel A. Dmochowski
We develop an optimal version of a prior two-stage channel estimation protocol for RIS-assisted channels. The new design uses a modified DFT matrix (MDFT) for the training phases a…
Efficient Optimization Techniques for RIS-aided Wireless Systems
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski +1
The objective of this paper is to develop simple techniques to enhance the performance of multi-user RIS aided wireless systems. Specifically, we develop a novel technique called \…
Phase Dependent Loss Analysis for RIS Systems
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski
In this paper we focus on phase dependent loss (PDL), an important aspect of reconfigurable intelligent surfaces (RIS) where the signals reflected from the RIS elements are attenua…
