Optimal Beamforming for MISO Communications via Intelligent Reflecting Surfaces

Understand

Wireless communications via intelligent reflecting surfaces (IRSs) has received considerable attention from both academia and industry.

• In particular, IRSs are able to create favorable wireless propagation environments with typically low-cost passive devices.
• While various IRS-aided wireless communication systems have been investigated in the literature, thus far, the optimal design of such systems is not well understood.
• In this paper, IRS-assisted single-user multiple-input single-output (MISO) communication is investigated.
