A Novel Index Modulation Dimension Based on Filter Domain: Filter Shapes Index Modulation [PDF]
IEEE Transactions on Communications, 2021 A 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. This FSIM scheme allows a higher Spectral Efficiency (SE) gain than the time and frequency IM dimensions in Single-Input Single ...

Simplified double switching SVPWM implementation for three-level VSI
The Journal of Engineering, 2019 A generalised space vector pulse width modulation (SVPWM) framework for the realisation of all double switching states with a memory-optimised method is proposed to reduce the total harmonic distortion (THD) and to provide neutral point voltage balancing

CoRR, 2014 Index modulation, where information bits are conveyed through antenna indices (spatial modulation) and subcarrier indices (subcarrier index modulation) in addition to information bits conveyed through conventional modulation symbols, is getting increased research attention.

OFDM With Hybrid Number and Index Modulation [PDF]
IEEE Access, 2020 A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division multiplexing (OFDM) subblock. The proposed scheme is different from the conventional OFDM-subcarrier number modulation (OFDM-SNM)

Wind Farm Noise—Modulation of the Amplitude
Acoustics, 2021 The operation of a wind turbine results in a series of pulses where there is a significant instantaneous increase in the amplitude of the pressure signal, dependent upon the wind speed at the turbine blades.

Knot modules and the Nakanishi index [PDF]
Proceedings of the American Mathematical Society, 2002 This paper is concerned with a knot invariant called the Nakanishi index. It is defined as the size of the smallest square matrix which presents the knot module as a \(\mathbb{Z}[t, t^{-1}]\)-module. This invariant seems to have first been defined by Kawauchi who proved that it coincides with the size of a minimal generating set for the knot module ...

Space-Time Index Modulation [PDF]
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017 In this paper, we present a new multi-antenna modulation scheme, termed as {\em space-time index modulation (STIM)}. In STIM, information bits are conveyed through antenna indexing in the spatial domain, slot indexing in the time domain, and $M$-ary modulation symbols. A time slot in a given frame can be used or unused, and the choice of the slots used
