Index Modulation Multiple Access
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018In this paper, the use of index modulation (IM) technique for non-orthogonal multiple access (NOMA) is presented, called the Index Modulation multiple access (IMMA). From the concept of index modulation, IMMA technique uses the active subcarriers and inactive subcarriers to make index indices.

Chapters 2, 3, and 4 discuss how index modulation operates based on constellation and code resources. In this chapter, we focus on the implementation of pilot-based index modulation for orthogonal frequency division multiplexing (OFDM). The idea of information-guided pilot insertion OFDM (IGPI-OFDM) is proposed, in which the pilot positions are ...

Joint Delay-Doppler Index Modulation for Orthogonal Time Frequency Space Modulation
IEEE Transactions on CommunicationsOrthogonal time frequency space (OTFS) is a promising waveform with outstanding performance in doubly-selective channels. Spreading information symbols across the entire delay-Doppler plane enables OTFS to exploit full diversity. Nevertheless, there is a

Deep Learning-Based Detector for Dual Mode OFDM With Index Modulation
IEEE Wireless Communications Letters, 2021In this letter, we propose a deep learning-based dual mode orthogonal frequency division multiplexing with index modulation (DM-OFDM-IM) detector called DeepDM, which is close to optimal bit error rate (BER) performance with low computational complexity.

Differential Subcarrier Index Modulation
IEEE Transactions on Vehicular Technology, 2018One of the main challenges in orthogonal frequency division multiplexing (OFDM)–subcarrier index modulation (SIM) systems is the huge amount of resources required to obtain channel state information at the receiver side. In this paper, a differential subcarrier index modulation (DSIM) scheme is proposed, which entirely avoids the need for any channel ...

Polar codes with short code length under successive cancellation (SC) decoding are inferior to other advanced codes of similar block length. Although more sophisticated algorithms, such as SC list (SCL) decoding and SC stack (SCS) decoding were introduced to address the problem, the complexity of these algorithms has also increased.

Index Modulation Based Frequency Hopping: Anti-Jamming Design and Analysis
IEEE Transactions on Vehicular Technology, 2021Reactive symbol-level jammer has attracted attention due to its low energy cost and high jamming efficiency. With the development of software-defined radio (SDR), the implementation of reactive symbol-level jamming has become more practical and efficient.
