Green communication systems via a wavefront multiplexing technique

Systems Engineering, Volume 28, Issue 1, Page 5-14, January 2025.
Abstract A green communication scheme using an orthogonal wavefront (WF) multiplexing (Muxing) scheme spatially combined with orthogonal frequency‐division multiplexing (OFDM) techniques is proposed. It forms a spatial WF OFDM transceiver. The WF Muxing technique serves as the preprocessing and postprocessing method of the WF OFDM transceiver.
