Index and Composition Modulation [PDF]
IEEE Communications Letters, 2021 In this paper, we propose a novel modulation concept which we call \emph{index and composition modulation (ICM)}. In the proposed concept, we use indices of active/deactive codeword elements and compositions of an integer to encode information. In this regard, we first determine the activated codeword elements, then we exploit energy levels of these ...

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 ...

Sparse-Encoded Codebook Index Modulation [PDF]
IEEE Transactions on Vehicular Technology, 2020 Ultra-reliable and low-latency communications (URLLC) partakes a major role in 5G networks for mission-critical applications. Sparse vector coding (SVC) appears as a strong candidate for future URLLC networks by enabling superior performance in terms of bit error rate (BER).

Linear Precoded Index Modulation [PDF]
IEEE Transactions on Communications, 2019 Index modulation (IM) is an attractive concept for next generation communication systems. However, as an emerging technique, there are still some challenges need to be tackled in this frontier. In this paper, we consider two aspects of IM, which are diversity and detection complexity.
