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.

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 and Constellation Order Lowering for OFDM With Index Modulation

IEEE Communications Letters, 2020
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a promising variant of OFDM where indices of symbol carrying sub-carriers also convey information bits besides the complex symbols themselves. Recently, a lower order modulation variant has been proposed for OFDM-IM, where the baseband constellation is lowered with ...

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.
