Highly Efficient MIMO‐OFDM with Index Modulation
Wireless Communications and Mobile Computing, 2022 Index modulation (IM) is a novel digital modulation technique, which inactivates some subcarriers in orthogonal frequency division multiplexing (OFDM) to exploit the indices of the subcarriers to transmit bits implicitly, and has potential to further improve the energy efficiency and error performance.
