OFDM-IM Performance Evaluation Under Jamming Attack
2020 30th International Telecommunication Networks and Applications Conference (ITNAC), 2020Orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM) conveys extra information bits by the active subcarrier indices that are selected according to input bits. OFDM-IM is a strong transmission technology candidate for the next-generation networks, due to its performance gain over OFDM.

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.

Noncoherent OFDM-IM and Its Performance Analysis
IEEE Transactions on Wireless Communications, 2018In conventional orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM), the active subcarriers can convey information bits by modulated symbols as well as their indices. To detect modulated symbols, coherent detection is usually considered, which requires the channel state information (CSI) estimation for all subcarriers at a

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.

Noncoherent Detection for Improving the Spectral Efficiency of OFDM-IM Systems
Wireless Personal Communications, 2020Today, Orthogonal Frequency Division Multiplexing (OFDM) is the most preferred and commonly used scheme for all communication systems. A new multicarrier technique called OFDM with Index Modulation (OFDM-IM) has been developed recently where the indices of the active subcarriers are used to transmit information in addition to the constellation symbols.

Error Probability Analysis of OFDM-IM With Carrier Frequency Offset
IEEE Communications Letters, 2016OFDM-IM, which uses the indices of active subcarriers to carry additional information bits, is a novel multi-carrier transmission technique. In this letter, by exploiting the special design of OFDM-IM, we propose an analytical approach to evaluate the error probability of OFDM-IM subject to carrier frequency offset (CFO) in fading channels, where the ...
