Novel Index Modulation Techniques: A Survey [PDF]

open access: yesIEEE Communications Surveys and Tutorials, 2019
In fifth generation wireless networks, the escalating teletraffic and energy consumption has necessitated the development of green communication techniques in order to further enhance both the system’s spectral efficiency and energy efficiency. In the past few years, the novel index modulation (IM) has emerged as a promising technology that is widely ...

Generalized Space-and-Frequency Index Modulation [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2016
Unlike in conventional modulation where information bits are conveyed only through symbols from modulation alphabets defined in the complex plane (e.g., quadrature amplitude modulation (QAM), phase shift keying (PSK)), in index modulation (IM), additional information bits are conveyed through indices of certain transmit entities that get involved in ...

Index Modulated Polar Codes

2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020
Polar codes with short code length under successive cancellation (SC) decoding are inferior to other advanced codes of similar block length. Although more sophisticated algorithms, such as SC list (SCL) decoding and SC stack (SCS) decoding were introduced to address the problem, the complexity of these algorithms has also increased.

Differential Subcarrier Index Modulation

IEEE Transactions on Vehicular Technology, 2018
One of the main challenges in orthogonal frequency division multiplexing (OFDM)–subcarrier index modulation (SIM) systems is the huge amount of resources required to obtain channel state information at the receiver side. In this paper, a differential subcarrier index modulation (DSIM) scheme is proposed, which entirely avoids the need for any channel ...

Subcarrier-index modulation OFDM

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
A new transmission approach, referred to as subcarrier-index modulation (SIM) is proposed to be integrated with the orthogonal frequency division multiplexing (OFDM) systems. More specifically, it relates to adding an additional dimension to the conventional two-dimensional (2-D) amplitude/phase modulation (APM) techniques, i.e. amplitude shift keying (

Index Modulation Multiple Access

2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018
In this paper, the use of index modulation (IM) technique for non-orthogonal multiple access (NOMA) is presented, called the Index Modulation multiple access (IMMA). From the concept of index modulation, IMMA technique uses the active subcarriers and inactive subcarriers to make index indices.

Filtered OFDM with Index Modulation

2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018
In this paper, a novel multicarrier modulation scheme called Filtered Orthogonal Frequency Division Multiplexing with Index Modulation has been proposed for operation over frequency-selective and rapidly time-varying wireless fading channels. The filtering helps restricting the Out-of-Band Emission and indexing helps in reducing Transmitter Power.

Modulated index structures

Journal of the Optical Society of America A, 1990
We present a brief tutorial overview of the basic physics of periodically modulated index structures and how they affect an incident electromagnetic wave in various simple limits. Discussions of the wave-vector spectrum, coupled-amplitude equations, and finite grating-size effects are included.

Modulated-index structures

Annual Meeting Optical Society of America, 1988
This tutorial concentrates on how grating (modulated-index) structures are used in thin-film optics. The basic concepts of reflection and transmission through grating structures, consisting either of multiple layers or periodic structures in a film surface, are presented. The use of gratings in linear and nonlinear integrated optics is introduced.
