Intelligent reflecting surface‐aided network planning
IET Communications, 2022 Abstract Intelligent reflecting surface (IRS) composed of a large number of low‐cost, phase‐adjustable passive reflecting elements, which is an attractive solution of overcoming the signal attenuation and interference. IRS can be used as a low‐power passive system with signal enhancement and interference suppression.
