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 ...

Pilot-Based Index Modulation [PDF]
, 2021 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 ...

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.

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.
