Spatial Modulation for Generalized MIMO: Challenges, Opportunities, and Implementation [PDF]

open access: yesProceedings of the IEEE, 2014
A key challenge of future mobile communication research is to strike an attractive compromise between wireless network's area spectral efficiency and energy efficiency. This necessitates a clean-slate approach to wireless system design, embracing the rich body of existing knowledge, especially on multiple-input-multiple-ouput (MIMO) technologies.

Flexible Generalized Spatial Modulation for Visible Light Communications

open access: yesIEEE Transactions on Vehicular Technology, 2021
Adaptive spatial modulation (ASM) varies the modulation size across the transmit light-emitting diodes (LEDs) to improve the overall spectral efficiency of visible light communication (VLC) systems. This article proposes a novel ASM scheme, referred to as flexible generalized spatial modulation (FGSM), for VLC systems.

RIS-Aided Receive Generalized Spatial Modulation Design with Reflecting Modulation [PDF]

open access: yesGLOBECOM 2024 - 2024 IEEE Global Communications Conference
Spatial modulation (SM) transmits additional information bits by the selection of antennas. Generalized spatial modulation (GSM), as an advanced type of SM, can be divided into diversity and multiplexing (MUX) schemes according to the symbols carried on the selected antennas are identical or different. Recently, reconfigurable intelligent surface (RIS)

Differential Transmission Schemes for Generalized Spatial Modulation [PDF]

open access: yesIEEE 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

open access: yesIEEE 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.

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]

open access: yes, 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.

Iterative generation of holograms on spatial light modulators [PDF]

open access: yesOptics 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.
