In fifth generation wireless networks, the escalating teletraffic and energy consumption has
necessitated the development of green communication techniques in order to further …

In this treatise, we provide an interdisciplinary survey on spatial modulation (SM), where
multiple-input multipleoutput microwave and visible light, as well as single and multicarrier …

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 …

We propose a new index-modulation-aided differential chaos shift keying (DCSK) system
using frequency-and-time resources, referred to as CTIM-DCSK system, to achieve high …

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 …

A new differential chaos shift keying scheme with multidimensional index modulation,
referred to as MIM-DCSK scheme, is proposed in this paper. This design objective of the …

This paper provides a comparative study on the performance of different modulation options
for orthogonal frequency division multiplexing (OFDM) in terms of their spectral efficiency …

The wireless revolution has already started with the first official 3GPP release of 5G wireless
networks, which is expected to support a plethora of applications. Despite the development …

In this paper, we investigate indexing of delay-Doppler (DD) bins in orthogonal time
frequency space (OTFS) modulation and propose indexing designs that enhance the …

A novel transmission scheme is introduced for efficient data transmission by conveying
additional information bits through jointly changing the index and number of active …
