Sequency Index Modulation: A Novel Index Modulation for Delay-Sequency Domain Waveforms
IEEE Wireless Communications Letters, 2023In this letter, the sequency domain is introduced as a novel resource to propose a new index modulation, which is named sequency index modulation (SeIM). In SeIM, information bits are implicitly conveyed through the indices of the activated sequencies enabling bit error rate (BER), spectral efficiency, and power efficiency enhancement.

Generalized Spatial Modulation With Multi-Index Modulation
IEEE Communications Letters, 2020In this letter, we propose a novel scheme extending index dimension with two distinct signal constellations, named as generalized spatial modulation with multi-index modulation (GSM-MIM). Through this scheme, which exploits the spatial domain and index domain, more extra information bits are transmitted by the spatial indexes as compared with the ...

2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020
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.

Filtered OFDM with Index Modulation
2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018In this paper, a novel multicarrier modulation scheme called Filtered Orthogonal Frequency Division Multiplexing with Index Modulation has been proposed for operation over frequency-selective and rapidly time-varying wireless fading channels. The filtering helps restricting the Out-of-Band Emission and indexing helps in reducing Transmitter Power.

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 ...
