Coded OFDM-IM with iterative detection☆

AEU - International Journal of Electronics and Communications, 2020
Abstract Coded Orthogonal frequency division multiplexing with index modulation (OFDM-IM) has been proposed, where channel coding and soft decision are employed to exploit the multipath diversity for the information conveyed by the constellation symbols. However, the performance of coded OFDM-IM is dependent on the detection performance of subcarrier

OFDM-IM Performance Evaluation Under Jamming Attack

2020 30th International Telecommunication Networks and Applications Conference (ITNAC), 2020
Orthogonal 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.
