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.

Super-Mode OFDM With Index Modulation [PDF]
IEEE Transactions on Wireless Communications, 2020 Orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM) appears as a promising multi-carrier waveform candidate for beyond 5G due to its attractive advantages such as operational flexibility and ease of implementation. However, OFDM-IM may not be a proper choice for 5G services such as enhanced mobile broadband (eMBB) since ...

Polar-Coded OFDM With Index Modulation
IEEE Access, 2021 In this paper, we apply polar codes to a modified version of OFDM systems with index modulation which is called OFDM with in-phase/quadrature index modulation (OFDM-I/Q-IM).

DCT-OFDM With Index Modulation [PDF]
IEEE Communications Letters, 2017 In this letter, index modulation (IM) is proposed for OFDM systems based on a discrete cosine transform (DCT) implementation. The new DCT-OFDM-IM scheme is shown to yield spectral efficiency improvements of up to 38% relative to OFDM-IM and up to 55% relative to OFDM while occupying the same bandwidth and maintaining similar robustness against the ...

Filter Shape Index Modulation [PDF]
ICC 2021 - IEEE International Conference on Communications, 2021 Index Modulation (IM) techniques enable a significant Spectral Energy (SE) and/or Energy Efficiency (EE) enhancement. In this paper, a novel Filter IM domain is being explored, where a novel scheme Filter Shape Index Modulation (FSIM) is proposed. In contrast to most existing Single-Input Single-Output (SISO) IM systems, the proposed scheme achieves a ...

Hierarchical Multi-Functional Layered Spatial Modulation
IEEE Access, 2018 In pursuit of optimal index modulation -aided multiple-input multiple-output (MIMO) systems, where information is implicitly conveyed by relying on the on/off mechanism of the system's components in addition to the classical amplitude, phase, or ...

Enhanced Coordinate Interleaved OFDM With Index Modulation
IEEE Access, 2017 Orthogonal frequency-division multiplexing with index modulation (OFDM-IM) has attracted much attention in recent years. In OFDM-IM, the information bits of a block are generally divided into several subblocks, each of which is further split into two ...
