Joint Transmitter–Receiver Spatial Modulation
IEEE Access, 2018 We propose and investigate a joint transmitter-receiver spatial modulation (JSM) scheme, which transmits information by jointly exploiting the indices of transmit antenna patterns, the indices of receiver antennas, and amplitude-phase modulation.

IEEE Access, 2018 In this treatise, we present the concept of compressed-sensing (CS)-aided space-time shift keying index modulation (STSK-IM), where a virtual domain orthogonal frequency division multiplexing (OFDM) symbol is divided into Na-sized blocks, which carry K ...

On the Capacity and Performance of Generalized Spatial Modulation
, 2015 Generalized spatial modulation (GSM) uses $N$ antenna elements but fewer radio frequency (RF) chains ($R$) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with $R=1$ and $R=N$, respectively.

Spatial light modulators [PDF]
Photoniques, 2020 Spatial Light Modulators (SLMs) are quasiplanar devices, allowing for the modulation of the amplitude, phase and polarization, or a combination of these parameters of an incident light beam according to the two spatial dimensions of the modulator. SLMs are employed in many different fields and are the subject of continuous technological development.
