Optimal SNR Analysis for Single-user RIS Systems in Ricean and Rayleigh Environments
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski
We present an analysis of the optimal uplink (UL) SNR of a SIMO Reconfigurable Intelligent Surface (RIS)-aided wireless link. We assume that the channel between base station (BS) a…

Tight Bounds on the Optimal UL Sum-Rate of MU RIS-aided Wireless Systems
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski
The objective of this paper is to develop simple techniques to bound the optimal uplink sum-rate of multi-user RIS-aided wireless systems. Specifically, we develop a novel techniqu…
