Alternating Beamforming With Intelligent Reflecting Surface Element Allocation [PDF]

open access: yesIEEE Wireless Communications Letters, 2021
Intelligent reflecting surface (IRS) has become a promising technology to aid next generation wireless communication systems. In this paper, we develop an alternating beamforming technique with a novel concept of IRS element allocation for multiple-input multiple-output systems when a base station supports multiple single antenna users aided with a ...

Line-of-Sight MIMO via Intelligent Reflecting Surface

open access: yesIEEE Transactions on Wireless Communications, 2023
This paper deals with line-of-sight (LOS) MIMO communication via an intelligent reflecting surface (IRS). It is shown that the number of spatial degrees of freedom (DOF) afforded by this setting grows in proportion with the IRS aperture, as opposed to being dictated by the transmit and receive apertures; this buttresses the interest in IRS deployments ...
