Passive Beamforming Design for Intelligent Reflecting Surface Assisted MIMO Systems
Chenghao Feng, Wenqian Shen, Xinyu Gao +1
Intelligent reflecting surfaces (IRSs) constitute passive devices, which are capable of adjusting the phase shifts of their reflected signals, and hence they are suitable for passi…
