Space–frequency‐mode multi‐dimensional hybrid modulation for vortex wave MIMO‐OFDM systems
IET Communications, 2021 By exploiting a dimension called orbital angular momentum (OAM) modes, a new modulation scheme referred to as multi‐dimensional space–frequency‐mode hybrid modulation (SFMHM) is proposed in this paper, which aims to further improve the MIMO‐OFDM system's
