Hybrid Beamforming for Distributed Intelligent Reflecting Surfaces-Aided Systems

In this paper, a distributed multiple-intelligent reflecting surface (IRS)-assisted multiple-input single-output (MISO) system is studied. Since IRS is operated in a passive manner, only imperfect channel information is considered in our model. Our aim is to maximize the achievable sum rate of the system by adopting a hybrid construction where we jointly optimize the active transmit beamforming at...
