Space-Time Multiple-Mode Orthogonal Frequency Division Multiplexing With Index Modulation

open access: yesIEEE Access, 2017
Multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-IM) improves the spectral efficiency of the conventional OFDM-IM scheme by considering multiple distinguishable constellations for signal modulation.

Adaptive dual-mode OFDM with index modulation

open access: yes, 2018
With the integration of the index modulation concept, the popular OFDM has gained an appealing new dimension. However, OFDM with index modulation (OFDM-IM) causes a decrease in data rate for higher order modulations due to its unused subcarriers ...

Index Modulation Multiple-Access (IMMA): Efficient Techniques for Downlink Millimeter Waves Outdoor Channel

open access: yesIEEE Open Journal of Vehicular Technology, 2021
In this paper, we propose two new multiple-access schemes for downlink transmission based on the combination of orthogonal frequency division multiplexing (OFDM) with index modulation (IM), namely OFDM-IM.

Index Modulation for Modulation on Conjugate-Reciprocal Zeros (IM-MOCZ)

open access: yes
This paper investigates the application of Index Modulation (IM) to Modulation on Conjugate-Reciprocal Zeros (MOCZ) to enhance spectral efficiency (SE) in short packet communications. The proposed IM-MOCZ scheme splits an $N$-bit message into two streams: $N-K$ bits select one of $2^{N-K}$ uniquely designed codebooks, while the remaining $K$ bits are ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

On the capacity of the AWGN channel with mixed input sources

open access: yesFranklin Open
In this paper, we present an information-theoretic foundation for the index modulation (IM) systems, including an upper bound of the AWGN channel capacity with the IM input sources.

Low-Complexity Subcarrier-Wise Detection for MIMO-OFDM With Index Modulation

open access: yesIEEE Access, 2017
Multiple-input multiple-output orthogonal frequency division multiplexing with index modulation (MIMO-OFDM-IM) is a relatively new multicarrier transmission technique for the MIMO systems to achieve both energy and spectral efficiency.
