A key challenge of future mobile communication research is to strike an attractive
compromise between wireless network's area spectral efficiency and energy efficiency. This …

A new class of low-complexity, yet energy-efficient Multiple-Input Multiple-Output (MIMO)
transmission techniques, namely, the family of Spatial Modulation (SM) aided MIMOs (SM …

This paper proposes a new multiple-input-multiple-output (MIMO) technique called
quadrature spatial modulation (QSM). QSM enhances the overall throughput of conventional …

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 introduce a new spatial modulation (SM) technique using one or two active
antennas and multiple signal constellations. The proposed technique, which we refer to as …

In this paper, we contribute to the theoretical understanding, analysis, and design of spatial
modulation multiple-input–multiple-output (SM-MIMO) systems for transmit diversity without …

A pair of salient tradeoffs have driven the multiple-input multiple-output (MIMO) systems
developments. More explicitly, the early era of MIMO developments was predominantly …

Space shift keying (SSK) modulation and its extension, the generalized SSK (GSSK),
present an attractive framework for the emerging large-scale MIMO systems in reducing …

This paper develops a non-coherent index modulation (IM) system in which activation
patterns are characterized by multi-level block codes. We analyze performance of such a …

A novel detect-and-forward (DeF) relaying aided cooperative SM scheme is proposed,
which is capable of striking a flexible tradeoff in terms of the achievable bit error ratio (BER) …
