LDPC Decoding With Low Complexity for OFDM Index Modulation
IEEE Access, 2021 In this paper, the posterior probabilities of the low-density parity check (LDPC) coded bits are derived for the orthogonal frequency division multiplexing index modulation (OFDM-IM) system to reduce the implementation complexity of LDPC decoding without

Multi-Hop Index Modulation-Aided OFDM With Decode-and-Forward Relaying
IEEE Access, 2018 In this paper, we propose a multi-hop index modulation-aided orthogonal frequency-division multiplexing (IM-aided OFDM) system, which employs decode-and-forward (DF) relaying techniques to enable the transmission of information from source to destination

Packet-Level Index Modulation for LoRaWAN
IEEE Access, 2021 The long range wide area network (LoRaWAN) is one of the enabling technologies for low power wide area (LPWA) networks. In LoRaWAN, a node transmits its packet to a gateway (GW) in an autonomous and decentralized manner.

Direct characterization of the spatial effective refractive index profile in Bragg gratings
, 2005 We propose a pulse response method to directly characterize the phase of the spatial index modulation, including the dc refractive index distribution (distributed phase shift), discrete phase, and chirp of fiber Bragg gratings (FBGs).

Multidimensional index modulation in wireless communications [PDF]
2017 Information Theory and Applications Workshop (ITA), 2017 In index modulation schemes, information bits are conveyed through indexing of transmission entities such as antennas, subcarriers, times slots, precoders, subarrays, and radio frequency (RF) mirrors. Index modulation schemes are attractive for their advantages such as good performance, high rates, and hardware simplicity.

Tone-Index Multisine Modulation for SWIPT [PDF]
IEEE Signal Processing Letters, 2019 We propose a new simultaneous wireless information and power transfer (SWIPT) technique that embeds information bits in the tone-index of multisine waveforms. By varying the number of subcarriers of the transmitted bandwidth-constrained multisine signal, the proposed scheme enables efficient radio-frequency energy harvesting and low-complexity ...
