Generalized Multistream Spatial Modulation Based on Frequency-Phase Modulated Signals
IEEE Wireless Communications Letters, 2022In this letter, we present an approach to building a new generalized multistream spatial modulation system (GMSM), where the information is conveyed by the two active antennas with signal indices and using all possible active antenna combinations. The signal constellations associated with these antennas may have different sizes.

Novel detection schemes for generalized quadrature spatial modulation
International Journal of Communication Systems, 2021SummarySpatial Modulation (SM) is a technology that incorporates digital modulation and coding with multiple antennas to achieve high data rates along with improved energy efficiency. Quadrature spatial modulation (QSM), which extends the transmitted signals to in‐phase and quadrature domains, has recently been proposed to improve spectral efficiency ...

Media‐based single‐symbol generalized spatial modulation
International Journal of Communication Systems, 2019SummarySingle‐symbol generalized spatial modulation (GSM) improves upon the limitation of spatial modulation (SM) by reducing the number of required transmit antennas to achieve high data rates. In this paper, we investigate the application of media‐based modulation (MBM) based on radio frequency mirrors to single‐symbol GSM, with the aim of improving ...

On generalized spatial modulation for multiuser wireless communications
2017 14th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2017The recently proposed multiple-input multiple-output (MIMO) technique of spatial modulation (SM) has attracted a good deal of attention due to its low implementation and computational complexity, and the spectral efficiency and energy efficiency gains it offers over many conventional MIMO schemes.

Integer-Forcing Detection of Generalized Spatial Modulation
2018Generalized spatial modulation (GSM) activates more transmit antennas than spatial modulation to increase the spectral efficiency. Although the maximum likelihood (ML) detector is able to achieve the optimal performance, its exhaustive search leads to intractable computational complexity.

Performance Analysis and Optimization of Secure Generalized Spatial Modulation
IEEE Transactions on Communications, 2020Artificial noise (AN) is considered as a new physical layer technology to improve the security of wireless systems. In this paper, we investigate secure transmission of AN-aided generalized spatial modulation (GSM), which maintains the same hardware requirements at the transmitter as the conventional GSM.

Holographic contour generation by spatial frequency modulation
Applied Optics, 1982A contouring method by spatial frequency modulation using hologram interferometry is presented. The principle is that Young's fringes produced by tilting the illumination ray are modulated by the object shape and demodulated by tilting the observation ray to generate depth contours. The problems of fringe localization and visibility in the arrangements

Diffraction-based determination of the phase modulation for general spatial light modulators
Applied Optics, 2006We describe a characterization method based on diffraction for obtaining the phase response of spatial light modulators (SLMs), which in general exhibit both amplitude and phase modulation. Compared with the conventional interferometer-based approach, the method is characterized by a simple setup that enables in situ measurements, allows for ...

Antenna Grouping in Dual-Polarized Generalized Spatial Modulation
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017While multiple-input multiple-output (MIMO) is considered as the key enabling technology for high data rate wireless communications, it faces several major challenges in the 5th generation MIMO systems due to limited number of radio frequency (RF) chains and space restrictions. In light of this, generalized-spatial modulation (GSM) and dual- polarized (
