A Novel Index Modulation Dimension based on Filter Domain: Filter Shapes Index Modulation

open access: yes, 2021
International audienceA novel domain for Index Modulation (IM) named "Filter Domain" is proposed. This new domain generalizes many existing modulations and IM domains. In addition, a novel scheme "Filter Shape Index Modulation" (FSIM) is proposed.
