Abstract
The achievable performance of subcarrier-index modulation (SIM) is analyzed in terms of its minimum Euclidean distance, constrained and unconstrained average mutual information, as well as its peak-to-average power ratio (PAPR). Our performance investigations identify the beneficial operating region of the SIM scheme over its conventional orthogonal frequency-division multiplexing (OFDM) counterpart, hence providing general design guidelines for the SIM parameters. More specifically, an SIM scheme is shown to be beneficial for the scenario of a relatively low transmission rate below 2 b/s/Hz. In addition, we demonstrate that the PAPR of the SIM scheme is comparable with that of its OFDM counterpart under the idealized simplifying assumption of having Gaussian input symbols.

Index Modulation Techniques for Next-Generation Wireless Networks

TL;DR: Three forms of IM are investigated: spatial modulation, channel modulation and orthogonal frequency division multiplexing (OFDM) with IM, which consider the transmit antennas of a multiple-input multiple-output system, the radio frequency mirrors mounted at a transmit antenna and the subcarriers of an OFDM system for IM techniques, respectively.

Massive But Few Active MIMO

TL;DR: From the information-theoretic perspective, SM achieves capacity comparable to the open-loop MIMO capacity, although a subset of transmit antennas is activated in every channel use because both the channel coefficients and the input symbols carry information in SM.

Single-RF Spatial Modulation Requires Single-Carrier Transmission: Frequency-Domain Turbo Equalization for Dispersive Channels

TL;DR: A broadband single-carrier (SC) spatial modulation (SM)-based multiple-input-multiple-output (MIMO) architecture relying on a soft decision (SoD) frequency-domain equalization (FDE) receiver that attains a near-capacity performance with the aid of a three-stage concatenated SC-based SM architecture.

Spatial Modulation -- OFDM

TL;DR: A novel multiple antenna-OFDM transmission approach, called spatial modu-lation (SM)-OFDM is presented, which entirely avoids inter-channel interference at the receiver input, requires no synchronization between the transmitting antennas, and avoids correlation between them while maintaining high spectralency.
