Demystifying the Power Scaling Law of Intelligent Reflecting Surfaces and Metasurfaces
[article]
2019
arXiv
pre-print
Intelligent reflecting surfaces (IRSs) have recently attracted the attention of communication theorists as a means to control the wireless propagation channel. ...
We first prove analytically that mMIMO always provides higher SNRs, and then show numerically that the gap is substantial; a very large number of reflecting elements is needed for an IRS to obtain SNRs ...
One of these research directions relies on the use of an intelligent reflecting surface (IRS) [6] , also known as reconfigurable reflectarray [7] , software-controlled metasurface [8, 9] , and reconfigurable ...
