New Design of Constellation and Bit Mapping for Dual Mode OFDM-IM
IEEE Access, 2019 Dual mode orthogonal frequency division multiplexing with index modulation (DM-OFDM-IM) is recently proposed, where the subcarriers within each subblock are divided into two groups, which are modulated by two distinguishable signal constellations.
