DCT-OFDM With Index Modulation [PDF]

open access: yesIEEE 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 ...

Super-Mode OFDM With Index Modulation [PDF]

open access: yesIEEE 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 ...

Index coded PSK modulation [PDF]

open access: yes2016 IEEE Wireless Communications and Networking Conference, 2016
In this paper we consider noisy index coding problem over AWGN channel. We give an algorithm to map the index coded bits to appropriate sized PSK symbols such that for the given index code, in general, the receiver with large amount of side information will gain in probability of error performance compared to the ones with lesser amount, depending upon

Linear Precoded Index Modulation [PDF]

open access: yesIEEE 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.

Discrete Multitone Modulation for Maximizing Transmission Rate in Step-Index Plastic Optical Fibres [PDF]

open access: yes, 2009
The use of standard 1-mm core-diameter step-index plastic optical fiber (SI-POF) has so far been mainly limited to distances of up to 100 m and bit-rates in the order of 100 Mbit/s.

Precoder Index Modulation

open access: yesCoRR, 2014
Index modulation, where information bits are conveyed through antenna indices (spatial modulation) and subcarrier indices (subcarrier index modulation) in addition to information bits conveyed through conventional modulation symbols, is getting increased research attention.

Simplified double switching SVPWM implementation for three-level VSI

open access: yesThe Journal of Engineering, 2019
A generalised space vector pulse width modulation (SVPWM) framework for the realisation of all double switching states with a memory-optimised method is proposed to reduce the total harmonic distortion (THD) and to provide neutral point voltage balancing

OFDM With Hybrid Number and Index Modulation [PDF]

open access: yesIEEE Access, 2020
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division multiplexing (OFDM) subblock. The proposed scheme is different from the conventional OFDM-subcarrier number modulation (OFDM-SNM)
