Abstract

Intelligent reflecting surface is a new technology reconfigure the wireless propagation environment through intelligent signal reflection. In recent years, many studies have been done on the use of this technology in the wireless communication. In this article, we investigate one of the important points in the field of using this technology, which has been neglected until now. Since most of the times the signal sent in wireless and radar applications has modulation, it makes it difficult to create a signal with a desired phase at the receiver location. Because the reflected signal from the IRS may have a different delay than the signal received through the transmitter, and therefore the signal received from the transmitter and reflected from the intelligent surface have a different nature, so, strengthening or weakening the desired signal at the receiver location comes with difficulty. In this paper, we investigate this issue and suggest an innovative solution for the location of the intelligent reflecting surfaces in the environment to solve this problem in some applications.
