Codebook-based precoding for generalized spatial modulation with diversity
EURASIP Journal on Wireless Communications and Networking, 2019 This paper investigates codebook-based precoding for spatial modulation (SM) and generalized spatial modulation (GSM) systems. Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT).

Iterative generation of holograms on spatial light modulators [PDF]
Optics Letters, 1990 Iterative learning procedures on a hybrid electro-optic system can be employed to generate holograms on inexpensive liquid-crystal-television spatial light modulators. The algorithm takes into account random electronic noise in the system and compensates for spatial-light-modulator distortions.

Error probability and capacity analysis of generalised pre-coding aided spatial modulation [PDF]
, 2015 The recently proposed multiple input multiple output (MIMO) transmission scheme termed as generalized pre-coding aided spatial modulation (GPSM) is analyzed, where the key idea is that a particular subset of receive antennas is activated and the specific

A Unified Precoding Scheme for Generalized Spatial Modulation [PDF]
IEEE Transactions on Communications, 2018 Generalized spatial modulation (GSM) activates $n_{t}$ out of $N_{t}~(1 \leq n_{t} available transmit antennas, and information is conveyed through $n_{t}$ modulated symbols as well as the index of the $n_{t}$ activated antennas. GSM strikes an attractive tradeoff between spectrum efficiency and energy efficiency.

Improving Generalized Spatial Modulation Using Translation Patterns [PDF]
IEEE Communications Letters, 2020 Generalized spatial modulation (GSM) is a spectral-efficient technique used in multiple-input multiple-output (MIMO) wireless communications when the number of radio frequency chains at the transmitter is less than the number of transmit antenna elements.

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]
, 2013 In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.

Generalized Complex Quadrature Spatial Modulation [PDF]
Wireless Communications and Mobile Computing, 2019 Spatial modulation (SM) is a multiple-input multiple-output (MIMO) system that achieves a MIMO high spectral efficiency while maintaining the transmitter computational complexity and requirements as low as those of the single-input systems. The complex quadrature spatial modulation (CQSM) builds on the QSM scheme and improves the spectral efficiency by

Generalized Spatial Modulation in Highly Correlated Channels [PDF]
2019 IEEE 30th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC Workshops), 2019 Generalized spatial modulation (GSM) is a promising technique that can highly increase the spectral efficiency for ultra-high data rate systems. However, its performance degrades in highly correlated channels such as those in the millimeter wave (mmWave) and sub-Terahertz (sub-THz) bands.
