Integer-Forcing Detection of Generalized Spatial Modulation

2018
Generalized 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.

Novel detection schemes for generalized quadrature spatial modulation

International Journal of Communication Systems, 2021
SummarySpatial 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 ...

Hybrid Precoding Design for Secure Generalized Spatial Modulation With Finite-Alphabet Inputs

IEEE Transactions on Communications, 2021
Technically, the security performance of generalized spatial modulation (GenSM) networks can be enhanced by dynamically adjusting the precoder allocated to the legitimate signal as communication channel varies.

On generalized spatial modulation for multiuser wireless communications

2017 14th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2017
The 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.
