On the Capacity and Performance of Generalized Spatial Modulation [PDF]
IEEE Communications Letters, 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.

Differential Transmission Schemes for Generalized Spatial Modulation [PDF]
IEEE Transactions on Vehicular Technology, 2021 Differential modulation schemes are very relevant in receivers having power and processing limitations, as these schemes dispense with the need for knowledge of channel coefficients for symbol detection. Spatial modulation (SM) is a scheme used in multi-antenna transmission scenarios where the data is transmitted in the amplitude, phase and spatial ...

On the Capacity of Generalized Quadrature Spatial Modulation
IEEE Wireless Communications Letters, 2023 In this letter, the average mutual information (AMI) of generalized quadrature spatial modulation (GQSM) is first derived for continuous-input continuous-output channels. Our mathematical analysis shows that the calculation error induced by Monte Carlo integration increases exponentially with the signal-to-noise ratio.

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).

Peregrine comb: multiple compression points for Peregrine rogue waves in periodically modulated nonlinear Schr{\"o}dinger equations [PDF]
, 2015 It is shown that sufficiently large periodic modulations in the coefficients of a nonlinear Schr{\"o}dinger equation can drastically impact the spatial shape of the Peregrine soliton solutions: they can develop multiple compression points of the same ...

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.

Energy Efficient Transmission over Space Shift Keying Modulated MIMO Channels [PDF]
, 2012 Energy-efficient communication using a class of spatial modulation (SM) that encodes the source information entirely in the antenna indices is considered in this paper. The energy-efficient modulation design is formulated as a convex optimization problem,

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.
