What is index modulation (IM)? This is an interesting question that we have started to hear
more and more frequently over the past few years. The aim of this paper is to answer this …

In this paper, we propose a composite multiple-mode orthogonal frequency division
multiplexing with index modulation (C-MM-OFDM-IM) scheme to increase the spectral …

Index modulation (IM) provides a novel way for the transmission of additional data bits via
the indices of the available transmit entities compared with classical communication …

The main limitations of employing large-scale antenna (LSA) architectures for broadband
frequency-selective channels include, but are not limited to their complexity, power …

In this paper, we propose a novel scheme, which is called generalized precoding-aided
quadrature spatial modulation (GPQSM), that extends the conventional quadrature spatial …

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 …
