Abstract
In this paper, a frequency mixing and modulating controller (FMMC)-reconfigurable intelligent surfaces (RISs) based architecture is proposed or multi-carrier communication. We consider an RIS equipped with FMMC, which is capable of modulating the symbol to be transmitted using multiple frequencies over the carrier received from the base-station. This allows the transmission of multiple signals over multiple subcarriers, resulting in the communication scenario similar to conventional orthogonal frequency division multiplexing (OFDM). The possible application of the proposed architecture is also discussed.
