PAPR Reduction for OFDM-IM: An Enhanced Active Constellation Extension Method
UK, Europe, China Millimeter Waves and THz Technology WorkshopOrthogonal frequency division multiplexing with index modulation (OFDM-IM) outperforms conventional OFDM in bit error rate (BER) at low-to-medium rates and resists inter-carrier interference in fast-varying channels. However, it suffers from high peak-to-

Coded OFDM-IM With Transmit Diversity
IEEE Transactions on Communications, 2017In this paper, we propose a simple transmit diversity scheme for orthogonal frequency division multiplexing (OFDM) with index modulation (IM) in order to achieve a diversity gain for index detection, which can significantly improve the performance of OFDM-IM at the cost of the spectral efficiency.

Impact of Channel Estimation on The Performance of OFDM-IM With Barrage Jamming
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020Orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM), which transmits information bits both by M-ary constellation symbols and indices of active subcarriers that are selected according to input bits, has attracted the attention of researchers in the recent years.

Golden Angle Modulation Aided OFDM-IM for an Arbitrary Number of Subcarriers
IEEE Communications Letters, 2023In this letter, we propose golden angle modulation aided orthogonal frequency division multiplexing with index modulation (OFDM-IM-GAM) for an arbitrary number of subcarriers, which includes integer OFDM-IM-GAM (I-OFDM-IM-GAM) and fractional OFDM-IM-GAM (

Constellation Design for Dual-Mode OFDM-IM
2020 Fourth International Conference on Computing Methodologies and Communication (ICCMC), 2020Dual mode Orthogonal Frequency Division Multiplexing with Index Modulation (DM-OFDM-IM) is a modified version of the orthogonal frequency division multiplexing with index modulation (OFDM-IM). In DMOFDM-IM, sub-carriers in each sub-block are divided into two groups.
