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 communications are considered. Specifically, we first review the permutation modulation (PM) concept, which was originally proposed by Slepian in 1965. The PM concept has been applied to a wide range of applications, including wired and wireless communications and data storage. By introducing a three-dimensional signal representation, which consists of spatial, temporal and frequency axes, the hybrid PM concept is shown to be equivalent to the recently proposed SM family. In contrast to other survey papers, this treatise aims for celebrating the hitherto overlooked studies, including papers and patents that date back to the 1960s, before the invention of SM. We also provide simulation results that demonstrate the pros and cons of PMaided low-complexity schemes over conventional multiplexing schemes.

“…Index modulation (IM) [1]- [3], which employs the activate indices as well as Amplitude Phase Modulation (APM) symbols to convey information, is a recently developed high spectral digital modulation scheme. It has been widely used in the antenna-domain [4], code-domain [5] and subcarriers-domain [6].…”

Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (OFDM-IM), which conveyed information bits via the activated indices and constellation symbols is a promising technique in the next wireless communications. In the OFDM-IM scheme, only part of subcarriers are activated to transmit information, the inactive subcarriers transmit zero symbols, so that the conventional differential coding is not suitable for the adjacent subcarriers. In order to address this issue, in this paper, a novel Rectangular Differential OFDM-IM (RD-OFDM-IM) scheme is proposed to exploit the benefits of OFDM-IM dispensing with Channel State Information (CSI). In the proposed RD-OFDM-IM scheme, N subcarriers are partitioned into G subblocks and index modulation is employed in each subblock first. Then rectangular differential coding is invoked during two adjacent subblocks, so that nocoherent detection can be employed for the proposed RD-OFDM-IM scheme. Simulation results are shown that the proposed RD-OFDM-IM scheme is capable of providing considerable performance gain over conventional Differential OFDM (D-OFDM) scheme with lower Peak Average Power Ratio (PAPR).

“…Index modulation (IM) [11] [12] is an emerging concept, in which extra information bits are mapped to the indices of multiple transmission resources [11] [13], such as the indices of antennas [13] [14], subcarriers [15] or time slots [13]. Spatial Modulation (SM) [3] [16] constitutes a promising MIMO technique, which transmits information bits mapped to the indices of the active transmit antennas, which corresponds to exploiting the spatial domain.…”

“…Additionally, OFDM-IM is also combined with MIMO techniques in [24] and [25], which are proposed as promising energy-efficient 5G wireless communications systems. The recent studies in [13], [26] and [27] have explored IM in different dimensions, where an improved error performance has been obtained by increasing the number of dimensions applied.…”

Abstract-In space-time shift keying (STSK), the information is conveyed by both the spatial and time dimensions, which can be used to strike a trade-off between the diversity and multiplexing gains. On the other hand, orthogonal frequency division multiplexing (OFDM) relying on index modulation (IM) conveys information not only by the conventional signal constellations as in classical OFDM, but also by the indices of the subcarriers. In this paper, we combine the benefits of STSK and IM in order to strike a flexible trade-off between the throughput and bit-error performance by transmitting extra information bits in each subcarrier block, whilst increasing the diversity order. In order to further improve this trade-off, as well as to decrease the complexity of the detector, compressed sensing (CS) is combined with the proposed STSK-aided IM system. We first present the Maximum LikeLihood (ML) detection, which forms the best-case bound on the proposed system's performance. Then we propose a pair of reduced-complexity detection algorithms capable of approaching the ML detector's performance. Furthermore, in order to attain a near capacityperformance, we propose a soft-input soft-output (SISO) decoder that is capable of exchanging soft-information with a channel decoder through iterative decoding.
