Novel Index Modulation Techniques: A Survey (2019, positive): “2) Single-Mode Class: In [39], subcarrier-index modulated OFDM (SIM-OFDM) was proposed, where part of the subcarriers are modulated by QAM, and the indices of these activated subcarriers in each OFDM symbol or block are determined by the corresponding majority bit-values of an onoff-keying (OOK) dat”
Orthogonal frequency division multiplexing with index modulation (2012, methodology): “Unlike the scheme of [3], feedforward signaling from transmitter to the receiver is not required in our scheme in order to successfully detect the transmitted information bits.”
Spatial Modulation for Generalized MIMO: Challenges, Opportunities, and Implementation (2014, background): “Inspired by [53], [55], and [91], various encoding mechanisms, link-adaptation schemes, and transmit-preprocessing solutions have been proposed [95]–[142].”
A Survey on Spatial Modulation in Emerging Wireless Systems: Research Progresses and Applications (2019, methodology): “Frequency Domain Subcarriers SIM-OFDM [240], OFDMIM [98], OFDM-I/Q-IM [241], GFDM-IM [242] Higher spectral efficiency& higher energy efficiency”
Index Modulation Techniques for Next-Generation Wireless Networks (2017, methodology): “Inspired by the SM concept, a primitive subcarrier IM-OFDM scheme is proposed in [350], in which each subcarrier carries one additional IM bit and the subcarriers associated with the majority bit value (0 or 1) are activated.”
