Channel Capacity Optimization Using Reconfigurable Intelligent Surfaces in Indoor mmWave Environments

Understand

Indoor millimeter-wave (mmWave) environment channels are typically sparsely-scattered and dominated by a strong line-of-sight (LOS) path.

• Therefore, communication over such channels is in general extremely difficult when the LOS path is not present.
• However, the recent introduction of reconfigurable intelligent surfaces (RISs), which have the potential to influence the propagation environment in a controlled manner, has the potential to change the previous paradigm.
• Motivated by this, we study the channel capacity optimization utilizing RISs in indoor mmWave environments where no LOS path is present.
