Future wireless communications look forward to constructing a ubiquitous intelligent information network with high data rates through cost-efficient devices. Benefiting from the tunability and programmability of metamaterials, reconfigurable holographic surface (RHS) composed numerous metamaterial radiation elements is being developed as promising solution fulfill such challenging visions. The ...

The contemporary wireless transmitter in addition to information symbols transmits also training order help the receivers estimation of by estimating channel state (CSI). In this paper, we look at existing communication technologies light environment-aware communications, which is a new concept communications that queries time-invariant CSI from local or global database, using about and receive...
