In this paper, we provide a comprehensive review of diverse index modulation (IM)
architectures that operate in the space, time, and frequency domains, as well as their related …

Quadrature spatial modulation (QSM) is recently proposed to increase the spectral efficiency
(SE) of SM, which extends the transmitted symbols into in-phase and quadrature domains. In …

Explores the fundamentals required to understand, analyze, and implement space
modulation techniques (SMTs) in coherent and non-coherent radio frequency environments …

Space modulation techniques (SMTs), in which some or all of the data bits modulate a block
of spatial constellation symbol, are promising candidates for future 5G wireless systems …

Space modulation techniques (SMTs) have emerged as promising candidates for spectral-
and energy-efficient wireless communication systems since they strike a good balance …

A novel generalized polarization-space modulation (GPSM) is proposed for polarized
multiple-input multiple-output (MIMO) systems with a limit number of radio frequency (RF) …

In space modulation techniques (SMTs), data bits are transmitted through modulating spatial
and signal symbols. Signal symbols are ordinary complex symbols drawn from an arbitrary …

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 …

Multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-
IM) improves the spectral efficiency of the conventional OFDM-IM scheme by considering …

We consider quadrature spatial modulation (QSM) schemes, which achieve high spectral
efficiency (SE) via the dispersion of a relatively small number of-ary modulated symbols over …
