OFDM With Interleaved Subcarrier-Index Modulation

IEEE Communications Letters, 2014
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a recently developed technique which modulates part of the information bits using the indices of OFDM subcarriers.

RIS-Aided Index Modulation for OFDM-IM Systems: Detection and Code Design

In this paper, a novel scheme of reconfigurable intelligent surface (RIS) aided index modulation (IM) for orthogonal frequency division multiplexing with index modulation (OFDM-IM) systems is proposed, where the RIS acts both as a passive reflecting surface and an additional information source.
