Coordinate Interleaved OFDM With Power Distribution Index Modulation
IEEE Communications Letters, 2022 Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which transmits information bits via $M$ -ary constellation symbols and indices of the active subcarriers, is a promising OFDM-based multicarrier transmission scheme.

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).

Knot modules and the Nakanishi index [PDF]
Proceedings of the American Mathematical Society, 2002 We examine the structure of the knot module of $9_{38}$ and show that the Nakanishi index of this knot is 2. The Nakanishi indices of $10_{69}$ and $10_{101}$ are also determined, by means of the Fox-Smythe row class. Finally, we point out that the Nakanishi index is not additive over knot composition.

Optimal Mapper for OFDM With Index Modulation: A Spectro-Computational Analysis
IEEE Access, 2020 In this work, we present an optimal mapper for OFDM with index modulation (OFDM-IM). By optimal we mean the mapper achieves the lowest possible asymptotic computational complexity (CC) when the spectral efficiency (SE) gain over OFDM maximizes.

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 ...
